The Rising Cost of Justice
Inhabiting a dimension which he rules without question Xastur’s true origins are unknown.
While he is imprisoned within his own ruined world that had done nothing to prevent him from making attempts to spread his influence to other universes. He has granted humans magical gifts, such as the Weird Sisters, in attempts to gather agents. He has also fathered several children who are able to cross over into our world, although they carry on the smallest fraction of his power.
Driven by a hunger for worship and more beings to serve him Xastur has made numerous attempts to shatter the barrier between our dimensions, but each attempt has met with failure. Should he ever fully emerge though he would be unstoppable.
