Guraf Hroason is a Nord found just outside the town of Senie. When you approach him, he sounds cautious, "Stranger, you've picked a bad time to visit Senie. The volcano's burning up the town! You'd think these thick-headed louts would accept some help." When you ask him who it is that doesn't want help, he replies, "These pissant Dunmer! I know an Argonian named Soft-Scale who can make a salve to soothe the injured, but Spellwright Girvas won't work with him or any Argonian." Ask him why and he sighs, "Because he's the most stubborn creature you'll ever meet. He needs to see these Argonians are on his side. If you want to help, Soft-Scale needs shalk chitin for his salve. Kill them and take the chitin to the Argonian. He's somewhere in town."
After accepting the quest, you can ask Guraf why the Argonians and Dunmer are arguing, to which he replies, "Bad blood. I thought everyone knew that. Back before the Ebonheart Pact was formed, Dark Elves enslaved Argonians. They raided the Black Marsh and brought the captives up here to work." When you mention that the Argonians must still resent that, he shrugs, "Sure, but the biggest problem is the Dunmer. They used to be lords and masters until the Pact was formed. Now all of a sudden, the Argonians are free and everyone is equal." Following his words, reply that it seems it is the former slavemasters who are having trouble adjusting. Guraf replies with a laugh, "Ha! Spoken like a courtier. You know, just saying everyone is friends doesn't make it so. Forming the Pact was a battle, and there are still many sides to it."
