Chief Engineer Derward

In Need of Supplies
When you reach a dead end in the quest, you find him alongside a group of dwarves. When you talk to him, he will say:


 * Derward: Ah, Jan must've sent you. You have some explosives for me?
 * You: Explosives?
 * Derward: Oh, sorry. Supplies is what Han likes to call them. He's a bit on edge about saboteurs and such since the accident in the southern excavation.
 * You: I see. Here you go.
 * Derward: Much obliged. C'mon, boys, let's set this charge up on that pile of rocks. I smell ancient Threnal gold just around the corner.

Talking to him after delivering the "supplies" will make him say:


 * Derward: What do you want, a medal? Get back to Jan before he sends a rescue party after you. Hah!

The Rescue
After fighting your way into the ruins, you meet him holding his position in a room deep into the ruins. Talking to him will make him say:


 * Derward: It's good to see you again. After the dust from the explosion settled, we were surrounded by gargoyles. I held them off while my men ran and was forced to hole up in this room.
 * You: Let's get you out of here. (He will follow you)
 * You: Stay here for now. (He will stand ground)
