In the last nine months, two mammoth tusks have been stolen in Seattle.
Obviously, there is a genie on the loose dolling out side quests.
I know what you're thinking
"How do you know it's not a main quest?"
Dude. It's a tusk. Those things take up sooo much weight in your inventory, and they're only ever worth, like, 15 gold. Tops. That's side quest nonsense.
