Also a bit of explanation as to why Osvin's death knights had sorrow loops.

Do note this was a plot point, and is written as such.

[quote]-The necromancer sets to work preparing the corpse, binding it with a spell of undeath that causes it to get progressively stronger the more grief and sorrow it causes, as well as more inhuman, essentially turning it into a sorrow based leech. This will have the additional effect of allowing the knight to feed off of his own grief, creating a sort of never-ending loop past a certain point that makes him stronger and stronger over time, much like the dread lords of old.[/quote]
