A Not So Evil God In Fate/Grand Order

Seth and Cu Chulainn could feel the tension in the air. This could mean one thing; the battle has already started. However, they decided to take their time to get there, not because they didn't want to help but because Seth needed to take it easy for now after telling his problems to Caster.

"This is definitely a big fight, not like the one from before." Cu said as he walked through the streets, even from their position, they could hear the shouts from the soldiers.

"It is, the negative emotions coming my way are enough to cover the sky." Seth agreed with Caster's words. It was indeed a significant conflict, even if the main forces of both parties were not involved.

"Must be tough, don't you get affected by that or something? Like going crazy and stuff." He asked with genuine curiosity.

"I was born from a place filled with the worst of evils known to humankind. In a sense, you can't corrupt what is already corrupted from the beginning." It was a desolated place, and the place he wished to return to.

"But didn't you went mad before? How did that happen, then?" To Cu Chulainn, his words made no sense.

"Do you know about this so-called 'Fallen Gods'? Gods that were inherently good or their authority was one that brought joy and happiness to the people, but once they were corrupted or their mind broke, they became a different, more evil kind of God?" He asked, and Caster nodded, he had heard some stories of it happening in the past although their veracity was unclear.

"The opposite is also possible, meaning that an evil God can actually transform into a kind and compassionate one. This is what we call 'Ascended Gods,' of course, the chance of the latter happening is lower than the former." His words certainly surprised Cu Chulainn. He didn't know something like that was possible.

"When that change happens, that God will get further and further from the authority that fundamentally complements his nature, be it good or evil. However, that comes at a cost. For example, a Fallen God will be affected by the new dark emotions around him, eventually leading him to madness. An Ascended God will lose his immunity to the same dark emotions, meaning he will get easily influenced by them and can possibly lead to getting corrupted. Of course, if one can adapt quickly to their new 'form,' then those consequences can be avoided."

Seth paused for a second before continuing. "Now, this is the most troublesome part. Fallen Gods, who returned to the side of Good, will be as weak as a mortal for a long time, depending on how long it takes for Good to forgive them. They usually get imprisoned by their fellow Gods until they are sure that particular God won't fall again. You can consider this a light punishment."

".. And what happens to Ascended Gods...what happened to you?" Cu Chulainn asked with a serious tone, knowing perfectly well that his next words will describe what Seth went through.

Putting his hands on his pocket, the God looked at the sky as if remembering long past memories. "Ascended Gods who get corrupted will take the worst of it all. Different from Good, Evil doesn't take kindly to the ones who discard it. The moment they get corrupted they can say goodbye to their sense of self, they will be nothing more than mindless beasts who will eventually be killed by other gods."

"The reason for me to become an Ascended God was the same reason why I got corrupted again, it was my servant who I grew up with who showed me the light, and it was his death the one that made me descend again." Seth released a long sigh, it worked to take a weight off his shoulders, but that didn't mean it was easy to talk about it.

"..." Caster didn't know what to say, Seth's words were spoken lightly, but he knew how hard it must be for him. It is never easy to tell others the worst parts of your life, always keeping them to oneself.

Even though Cu Chulainn was aware of it, it was necessary to continue. This will be good for Seth in the long run, one rainy day for a week of clear skies as they said.

"How is it that you are fine? I mean, I know you were killed, but for your words, those that are killed never return."

Seth couldn't help but wryly smile, listening to his words. "Evil doesn't show favoritism, that's what everyone thinks. However, that's far from the truth. To the majority of Dark Gods, Evil only thinks of them as nothing more than slaves who can be killed if they don't do their work or run away. But..."

"...but?" Caster motioned him to continue.

"There are ones who Evil will treat properly, Gods that fall in this category are usually known to most people; Loki, The Morrigan in your culture, Apophis, Hel, Azi Dahaka, among others."

"However, there is one more category, and there is only a single person who falls under it...and that person is me. These categories are like a pyramid, with one getting more benefits than the last." He explained to Cu Chulainn, who was listening attentively.

"By your words, do you mean to say that evil and good are self-conscious entities like Alaya? Also, how does it sees you?" It was shocking how two worlds could be so similar and, at the same time, so different.

"Evil and Good are ancient concepts which developed a conscience by themselves, they can speak and materialize as they wish and even strip the Authority and Divinity of a God if so they wished as their powers come originally from them. It's just that they usually stay as a concept and don't bother to make themselves known. As for how Evil sees me...It sees me as his own child. I really have some problems with father figures..."

The Celtic Hero couldn't help but release a light chuckle at his last words, making the atmosphere a bit lighter. "And why is it that Evil sees you like that?"

"... That is a question for another day. We have arrived." After a long walk, they got to the gate leading outside of the city where the battle was happening.

"I hope we didn't make the others wait too much." Cu Chulainn said as he walked past the running soldiers that were leaving the city to fight.

"They are Servants against normal humans. I doubt there is someone who could cause them problems. You don't have to worry." Seth just simply shook his head at his words.

"Strange things can happen, just sayin'. By the way, are you going to fight properly, finally?" He asked with a smirk on his face.

Seth looked at Caster with a confused look on his face. "What do you mean?"

"I have rarely seen you enjoy a fight, a warrior must always enter a battle to enjoy it, but you never do." The Sage of the Forest replied as a matter of fact.

"What are you talking about? I enjoyed my fight against Berserker, even though he wasn't properly summoned."

"You don't get it, do you? Your fight against Berseker was the first and proper one you had in thousands of years, that's why you enjoyed it, but later on, you lost the thrill that battle gives you." Sometimes he wondered how he could be so clueless about certain things.

"Is it that important?" He asked with raised eyebrows. "I don't feel like it has anything to do with saving Humanity."

"You already told me before; you are no King. So that leaves only one thing to be, a warrior. And a warrior must seek entertainment when fighting." He pointed at Seth with his staff to emphasize his point.

Seth just shrugged his shoulders at his words. "Whatever you say, but don't expect me to feel delight fighting against normal humans. However, I will give it a try as thanks for listening to my troubles." He didn't know why Cu was so fixed in him enjoying a fight, but he didn't lose anything trying, so might as well go along with it.

"Sometimes, it is hard to make you comprehend the simplest of things, I tell ya! Hahaha." Caster heartily laughed. To him, giving lectures to Seth was as fun as battling. It was also the only way he had to take revenge for the times he threatened with summoning his teacher, but he wouldn't say that out loud.

"I don't try to comprehend things I see as pointless but okay. Anyways, go ahead and join the battle. I will act as support this time." Sometimes talking with Cu Chulainn was exasperating for him.

"Yeah, yeah. Good luck with that!" After saying that, he took giant strides from the gate to the battlefield, the soldiers near were amazed at his capabilities, believing him to be some sort of sage. Even if they weren't exactly wrong about that.

"Well, now I suppose I will have to do my part." Seth disappeared without anyone noticing and reappeared a top of the walls where he could see the whole battlefield better.

To avoid any troublesome interactions, he put the archers near him in an illusion to make them think there was no one there apart from them.

Looking ahead, he was made aware of the scale of both armies. If nothing was done, the battle could be lasting for a couple of days with no clear winner. Seth also saw some explosions popping up here and there, meaning that the Servants were already killing enemy soldiers.

Taking a deep breath, his long hair started to sway slowly, and his eyes turned golden. "Come." With his command, the previously clear sky began to be covered by dark clouds out of nowhere.

Seth decided to summon a storm in the rear of the enemy line. He wasn't a God of Lightning, so he couldn't control precisely where it will fall, just the overall area. It was better to avoid summoning the storm near the frontlines.

The soldiers of both sides looked confused at the sudden appearance of the dark clouds. It looked like it would be a sunny day just a moment ago, after all. The enemy army even started having thoughts of it being a punishment from the Gods. Again, they weren't exactly wrong about that.

Different from the soldiers, the Servants knew precisely what this was. 'It seems Caster succeeded.' Jeanne thought while crushing an arrow directed to a soldier nearby as a small smile made its way to her face. Martha shared the same feeling as her while Jalter was happy, but for a different reason, she was going to see her Master massacre their enemies. Although she agreed to help Humanity, her hate for it had not gone away. Vlad looked at this from the point of view of a leader. For him, it was going to boost the morale of their soldiers and diminish the enemy's.

Rising his hand upward, the roar of thunder started being heard by the people below. Setting his gaze on the enemy army, he let his hand fall. As if it was a signal, a rain of lightning started falling on the enemy lines, causing havoc and burning every soldier unfortunate enough to be struck by it.

"It looks like Kuro-san already finished talking with Caster, that means he will be here soon." Fujimaru said after seeing the dark clouds in the distance.

"You are right, Senpai. I just hope Caster takes it easy, Lancelot and Kiyohime are not fighting at full strength to avoid draining you of your Magical Energy too much, and Vlad is concentrating on leading the army." Mash was in front of Fujimaru to block any arrows that came his way, fighting in the frontlines in a war like this was not ideal as she would have to attack and defend her Master at the same time, so they decided to stay at the backlines.

"It's okay, Mash. Although I'm not a hero or something like that I can understand how he feels, I don't mind giving some more Magical Energy than necessary if that makes him happy." He said with a smile as he rubbed the back of his head.

"You are really kind, Senpai. I'm really glad to be your Servant, I promise I will do my best to serve as your shield!" Mash said with a happy smile of her own.

Fujimaru laughed lightly in embarrassment at her words. "I don't think I deserve those words but thank you."

"Are you lovebirds done? You should pay more attention to the battle in front of you." Caster came just in time to hear their cheesy lines so he couldn't help but tease them about it.

"Y-You are wrong, we weren't—" Mash tried to explain herself with a red tint on her cheeks but was interrupted by Cu Chulainn.

"Sure, sure. Whatever you say, lass. Now, stay focused. We don't know when we can be surprised by the presence of a Servant with Presence Concealment." He decided to stop the teasing, for now, seeing how both of their faces were becoming the color of a tomato.

'Now, I should also join and defeat some enemies. Man, I really need to distract myself from that gloomy talk we had.' Thinking until there, Cu Chulainn moved to the opposite army's direction.
