How about if people could make descriptive suggestions & the synopsis of background for mythological creatures... Not to have them exist in game, but to make art of them & to tell the tales in rp etc..
I so far have only thought of basic silliness as ideas;
like the 9 tailed Giant Enki with tails going all up its spine whose legend says he saw since infancy that people were entranced by the hypnotic swaying of his tail, so he killed the rest of his litter, ripping holes in his own back to attach their tails before the nerves died... if you had seen him his tails would control your mind--and he could make you forget you ever saw him-- or remember but never be able to let anyone become aware that you had...
ok more an urban legend than a myth
how about Talad's Frankenkran of justice?--with one deady tef claw for an arm & one deadly ulber claw for an arm-- enki legs, klyros wings, elfish ears, ynwynn horns, (Nolthriir dorsal fin), rat tail and a dwarf's head...each part except the claws & tail fully loyal to talad in their life--cobbled together by a mad talad priest, brought to life by his mad quest thru deathrealm, where he slayed each again, then carried the bits together thru the portal... as they passed thru the portal it animated, and ate the insane priest, carrying out its own skewed image of talad's justice. Now it soars the skies of yliakkum looking for its next victim...
I know of at least one mentionned in klyros city thread --the seaweed something, it snatches babies
