Gregorovic

Gregorovic is a follower of Sliske in Runescape, being his general in the Heart Of Gielinor.

History
Gregorovic was not always a literal monster. He was a man that wished to discover the secret of immortality (as he was suffering from a terminal illness), so he decided to abduct some elves from the Cywir Clan and experiment on them, resulting in most of them dying.

This earned him the hatred of Helwyr, who would make it his mission to hunt him down for what he had done.
