Stealth Elf went on a mission to Rumbletown, and then, she never returned, so you went to search for her, and there, you saw her tied to a post, held by a Drow Goliath, and surrounded by Drow elves

Drow Goliath: "Well you look at that, a Skylander, now at our mercy, hahaha!"

Stealth Elf: "When I get out of here, I will kill all of you!"

Drow Elf: "Well, you can't there's no one here to save you... Hahaha!"
