The Entity's feeding method seems incredibly inefficient
I mean, think about it. It has to find a candidate for killer, twist and manipulate them mentally if they aren't already murderous, then pull them into its realm. Then it has to wait for people to stumble into the area of the atrocity and pull them in. And don't even get me started on the energy it would take to perform friggen necromancy, repeatedly, on beings with increasingly less and less to revive.
Seems like it'd be easier to hang out around colleege campuses during midterms and finals and then hibernate the rest of the year tbh.
