[@canaryrose] There's many reasons why, he hates Beacon. The Cult-like nature of Beacon and something from his past more to speak. Before what he became that is. Let's just say all these things will come out. He also thought Beacon was going to steal the Grail's he picked as his champion in the 12 and 13th Centuries. The Zargoth's Chosen. His paranoia is severe in that.

However, there's a person he hates MORE than Beacon and all the things within the list I posted that only had 3 certain things so far, aka Beacon, Puchuu and Lesser Forces.

The Post I am working on brings out somethings to light to who that person is.
