Orcus

Orcus is the Demon Lord of the Undead. After meeting with the Guardians of Grog and testing their worthiness he rewarded them with the Staff of Orcus, which they can use to defeat Scourge. He also requested that if the Guardians take the staff, in addition to the sun in Daisy Grove, to the center of the island he will reward them with a single wish.
