[Maltrease]

I like the idea of awards as well! They don't have to be huge, but given the strength of these horrors they not trivial to beat. You would need to almost build a custom SC built with the purpose of killing horrors and if so... why not have another advancement path to gain power.

I rather like the idea of gaining power and dominion in the Astral plain where these creatures and horrors reside.

Maybe there is some tie in to the void gate mechanics?
