Very Simply, when someone who wants dibs on a character with not many information, he posts here, along with the character he dibs on~... for example, I wanna be Ven, but what the heck is known about ven besides that he becomes as frost as a popsickle? x3 yup, that's right, DIBS HERE!
*and while your at it, feed my bloody egg xD*
Dibs on: Ven O.o''
