I had to check google for all of the realm names, and holy shite there are apparently 44 of them.
I would use a spoiler tag if I knew how to, but this will have to do:
Pirate, Deathmage, Spectre, Titan, Gorgon, Kraken, Satyr, Drake, Chimera, Dragon, Wyrm, Hydra, Leviathan, Minotaur, Mummy, Reaper, Phoenix, Giant, Unicorn, Harpy, Gargoyle, Snake, Cube, Goblin, Hobbit, Skeleton, Scorpion, Bat, Ghost, Slime, Lich, Orc, Imp, Spider, Demon, Blob, Golem, Sprite, Flayer, Ogre, Djinn, Cyclops, Beholder and Medusa
So pirates and deathmages has realm names, but not flying brains. FeelsBadMan
