A somewhat sinister character, Arstor is responsible for the creation of Purging Stones and the Shotel, and is linked to the various "bite rings", like the Cursebite, Bloodbite and Poisonbite Ring.
He is also known to have favored a spear which gave him the nickname of "impaler". He may also have used it to fight the Curse-rotted Greatwood, as the spear was found within the Greatwood's belly. Although said spear is enwreathed in poisonous meat, it is unknown if this was an effect of the Greatwood consuming it, or if it was part of the weapon when Arstor wielded it.
Arstor,Earl of Carim is based of off the iconic ruler Vlad Dracula also known as Vlad the Impaler.
