No, they belonged to that pirate who put the curse on his crew.

Edit. I just re-read the book on Deathbrand. The pirate captian did make a pact with Dagon, and a scar was placed on his face that would never heal. But the armor and weapons were made from Stal....... ore and did not belong to Dagon. At least that is what I gather from the book.

You can actually see Miraak's Sword during one of the loading screens where he stands there posing with it. Also, I've heard that he has a staff as well.

Bloodscythe, Soulrender I think they are meant to be ebony weapons because you need ebony to up grade them, but some one needs to paint them black. maybe it was over looked due to lack of time???????

I was under the impression the two swords might have been from Dagon due to the pact.

They might have been, but the book says he recieved a scar on his face that never heals from the pact. That is why I do not believe the swords are Dagon's. Could be wrong though.

"Lord Dagon, I wish to make a pact with you."

"What is it you desire?"

"Something to strike fear into the hearts of my foes."

"Fine, I'll give you this scar."

"You're...kidding, right? I just get this scar?"

"Hey, it looks pretty damn metal."

Sword of Dragonborn


IDK

Eh that's why you gotta be specific when dealing with deadra princes or they will just troll you.

Specifically, they would count for the achievement.

It would have been good to have more, for us xbox 360 users, since we are SOL if LOD or someone died (or if you picked a goody two shoes
option on another quest...) Then, 800 hours of play later, you realize you won't complete that achievement (even WITH getting TWO rewards
from the Hircine hunt one.) I'm still two short.

Quote from the book Deathbrand


"And the seal of that pact was the terrible wound that scarred his face, never to heal - the Deathbrand, which no man could look upon without flinching."


"All these years, I have looked for one who was worthy to take my place, or strong enough to take it from me. Not one of your even comes close. And so none of you shall have it."

He extended his hand. "In Dagon's name, I place a curse upon my armor, and my swords. This ship, and all it carries. Until the day when one of you can best me in combat, you shall have not a single coin." He looked up at them. "Be grateful I have left you with your lives."

The armor and swords were not Dagon's, only the curse placed unpo them.
