Okies, I saw the other post, which was absolutely ridiculous, or a very clever troll. I figured I'd just throw this here, and I'm sorry if most people already know or I'm not meant to make these sorts of posts.
I am 99% positive that Lord Anthrycist is not named after "The Antichrist", it is almost definitely based off of the word "anthracite".
Im sure of this because anthracite is a type of coal, a fitting name for a boss located in the Firelands, no?
Anthracite
an·thra·cite
-noun
A mineral coal containing little of the volatile hydrocarbons and burning almost without flame; hard coal.
