Corthen’s rust monster has arrived from the proprietor of the Old Monster Shop in Waterdeep. The moon elf hires some teamsters to take the caged rust monster out of town into the country. Corthen Nightglade then feeds the greater cursed long sword, as well as his other long sword to the rust monster since a remove curse spell could not remove the blade from his hand. This is effective at destroying the cursed sword that he found in Undermountain. Corthen then bribes the teamsters to keep their mouths shut about the event and and he returns the rust monster back to the Old Monster Shop for 1% of the 10,000 gold he paid for it.
