The Void Cloak is The Cloaked's cloak that only he can wear. If any other being tries to wear it, hey will be instantly teleported to a random location.
It does not have a set colour or shape, it just mainly takes the form of a purple cloak.
Does it really matter...? It's history after all.
- Invisibilty: All light that is around the cloak is instantly sucked into it. Hence, its invisibility feature. Though, higher beings can somehow 'shapeshift' out of the invisibility (not that they can wear it anyways).
- Pocket dimension (literally): Inside the cloak are pockets that contain pocket dimensions. The Cloak can store everything inside them, thus explaining him not having a vault.
- Why you gotta be so trivial?
