3rd Archive: Of More Power and a Dash of Responsibility

You can access this eternal battlefield by finding an ancient artifact within a dungeon. The time of the rest of the universe stops as you fight in the war, so that when you win it would be like nothing happened every where else. You don't have to worry about your new allies turning on you at the end, as they were all summoned on countless other planets and thus will not care about sending a monster back to Ruyanei with more power. On the topic of being a monster, the ranks of the Guardian armies are full of being that the Light of Ruyanei would have deemed dark, so as long as you don't go on a **** spree, then the army will welcome you with open arms.

All world choices will merely merge with Ruyanei, fusing the landscapes of both together, though Ruyanei will retain more of its recognizability.

CHAOS: Chaos magic is a powerful fundamental **** of reality. It represents potential and the outcome of uncountable factors. However, It must be used with **** caution, or you will succumb to the very chaos you wield. Chaos magic allows you to manipulate and reshape the fundamental fabric of reality, conforming it to your whims. This school is not banned, as its existence is only known to the most dangerous mages.

The world map can be applied to Ruyanei as the '**** Monster Isekai' have not shown one.
