Grayson Islands

unpredictable in terms of their actions

Not always.
I have a normal and adequate character, not some kind of crazy maniac.
Actually, I don't care. I'll be leveling up telekinesis and mind control.

Hero, and what will you be, a summoner or something?

Not really. I'll be controlling, transferring mana to allies through corpses, casting invisibility, and raising zombies. Although I might consider taking a golem, but it doesn't quite fit the image.
