Background
The Magorium Emporium is a shop of magical articles and remedies that has been a staple of the community for generations. Malory Magorium is the eccentric owner who supplies adventurers and mercenaries with her powerful implements and enchanted items. She has been recently contacted by a duke looking to subdue a massive horde of hobgoblins that are beginning to be a problem for his barony. This duke wants Malory to create a rod of lordly might for him, a legendary item that has great martial and magical powers. In order to fulfill the commission, Malory needs a strong arcane focus to enchant an item so powerful. Malory possesses such an arcane focus: a wand she keeps in a subterranean storage area. The only issue is the storage area is currently infested with a colony of mimics. Malory is at a loss for how they got in but regardless, she cannot take on the horde alone. She has been hoping to hire a group of adventurers who shop at her establishment to retrieve her wand for a heavy payment or exchange of goods.
