>>39369002He's an alien from a race that was summoned to help a tyrant take over the source of all magic. When they marched to war, he was the only one left to tend to their alien city and ate some magic mushrooms because he thought it would help him do the job of several people. It didn't and he accidentally shut the portal to his homeworld and before he could fix it, the tyrant accidentally the whole world. With the world fucked and the source of magic shattered, he can't open the portal again.
So he tricks YOU into breaking the world again, by tricking a different guy into thinking he is the dead tyrant reborn. Which means he can trick you into killing the new guy which will doublefuck the world, so the magic can get unfucked enough for him to fuse with the long dead tyrant and open the portal for his people again so they can eat all of the world's magic because they already ate all of their own.Just according to keikaku.
