ive been hearing alot about it and i havent found anything to do withe deathbrand armor in solsthiem. cans ome one give me directions?

I think you need to read the book titled "Deathbrand". That will trigger a misc quest in your log and point you in the right direction.

Look for books in Raven Rock titled Deathbrand. Pretty sure thats I got the first marker.

From what I know, there is an island with pirates on the east side just a little past midway. It started there for me.
