Goblins

Goblins are creatures of raw chaos, descended from Faerie-that-was; crude, weird, noble little blighters who have chaos all over their sticky little fingers into everything. In short, unpleasantness, pandemonium, and general mayhem - periodically invisible; pretty much toons, insofar as reality is taffy to them. Avoid.

Ecology
Related to the Gremlins, goblins originally hail from a form of fairyland before it became the Faerie Chaos and that their return to it led the Chaos to it's present state.

History
Goblins are unknown outside the halls of the users of magic, or nearly so. Every apprentice learns that goblins are the by-product of a thinning of the walls between the worlds and so it is common for the creatures to boil forth in the dedicated workspaces utilized by Wizards and Archmage ranked magic users.
