A company of Dragon-clan warriors is encamped at the northern end of the Gravenwood, marching down from Enedwaith.
'I have seen wagons bearing crates coming from the south to Uvel-cadlus. I wondered at first why the Dunlendings would be bringing provisions and supplies northward to a company that is moving southward towards their muster, but later I saw something that terrified me.
'The Draig-lûth took from the crates a black powder which they were able to ignite into a terrible fire which scorched tree and earth and shattered stone. I fear the Dragon-clan will use this black fire against our people, should all-out war ensue.
'Will you enter Uvel-cadlus and destroy this black fire? The Rohirrim would be greatly indebted to you if you should succeed.'
Crates of black fire can be found within Uvel-cadlus.
Thurbald has asked you to enter Uvel-cadlus and destroy the Draig-lûth's supply of black fire.
Thurbald is hiding to the south of Uvel-cadlus.
You should return to Thurbald with news of your success.
