Timeline: Late Pre-Ages --- Current
Wims are a large Supergroup of invertebrates consisting of 17 Groups, the group has adapted to various ecologies from the marine to the soil to the overground to the volcanoes themselves.
Wims are the oldest of Unikaria's creatures, originating in the late Pre-Ages roughly 788mya, although most of the ancient lineages died out by the tail end of the Lyfian Era, a couple of groups have survived since that period namely the Accursed and Ancient Groups. Wims are completely soft bodied minus a few hard growths some groups and species show that are of a hardened silk substance.
Wims began to reach larger sizes during the Lyfian Era to compete for food with the newer Supergroups that emerged since the Pre-Ages.
Evolving roughly 788mya they were the sole multicellular life on Unikaria for many millions of years until the Amorphians evolved just before the end of the Pre-Ages which brought great competition to the wims for the first tim
