Tasks

Kill King Demog and Take his Crown

Gugnir: Goblins. They're gonna kill us all!
Hero: What happened?
Gugnir: They killed everyone — my brothers and our five guards. They speared me good, left me for dead. I crawled here after they left. Their new king's got them all riled up, ready to attack Port Hunding and wipe out the town!
Hero: What can I do about it?
Gugnir: Kill their king! They won't attack the town without him to lead them. Bring me his crown so I know the bastard's dead. I'll try to make it to town, unless the Goblins kill me first.
Hero: I'll do it
Gugnir: I just need to gather my strength and hobble back to town. Get that Goblin king and bring me his crown, if you can!
Hero: How'd you run into the Goblins?
Gugnir: We actually went looking for them, if you can believe that. We'd heard they had a new king and that he was stirring up trouble. We figured we could handle them, but there were too many for us.
Hero: Why don't we just warn the town?
Gugnir: No good. Bhosek'll never believe it. He's a suspicious bastard and will think we're trying to trick him somehow. He'd have our heads on pikes. I'm too fond of my head to risk it.
Hero: What'll you do if I go after the king?
Gugnir: I'll try to make it to town. I'm too injured to be any good to you, and if the Goblins catch me out here, I'm dead.

Gugnir: Did you do it? Did you kill the Goblin king?
Hero: Yes. Here's the crown.
Gugnir: By Kyne, you did it! I've been expecting them to attack the town any minute. Bhosek tossed me out when I tried to warn him, said he'd have my head if I didn't shut up. He'll never know you saved his town for him.
