Heh. Your thoughts went exactly where mine did when I came up with these guys. There will be more coming forth, including spells that only Kolumaka can use (since they require a third eye), a Kolumakan domain, and a more in-depth explanation of just how the Beholder-Elf Horizontal Mambo happened. Probably a Kolumakan paragon class too.

And if you do want to use one of them, go right ahead. Just let me know how they play.
