Hosper
- This page is a temporary stub, because the concept that it covered came up enough to be worth explaining but we haven't had time to write a full article about it. It will eventually be replaced by a more in-depth article.
A hosper is the extent of space characterized by the same arcana; that is, magic works the same way within a given hosper. A hosper may encompass an entire plane or esture, but this is not always the case.
