Hammerspace
From Egs Mayhem
An interdimensional realm, or pocket universe, where unfeasibly large hammers are kept, in order to be magically produced as needed. Accessible only by women when something offensive towards females occurs, though it can also be used to defend men if they're just that androgynous.
It should be noted that while being hit with such a hammer does hurt very much, it does not deal any real damage.
Male Hammerspace
Where smaller hammers designed to make noise, construct and destroy assorted inanimate objects, and bruise thumbs are kept. Better known as a tool shed.
Inventory Hammerspace
Despite the name, this has nothing to do with hammers. This is a magical realm where a person’s inventory is sometimes kept. It is sometimes logically justified (May Cottontail uses a spell to conjure a hole in reality where her inventory is stored), and others’ are not (Joat Delia, for example).
Another form of this is the Magic Satchel, which is a container which can hold much more than it should be able to.
