I usually avoid making that kind of thread, but this mod is surprisingly hard to find.

Ward of Akavir, a Firemoth revision by Quorn.

-Found the original thread, download link is dead.
-Searched several hosting/list sites, no results.
-Searched for an alternative mod, found only an extreme version full of Deadras. (I'm searching for an improved challenge, not a grave. xP)
-Sent a message to Quorn on the forums. After a month, no reply.

My next option is to ask if someone still have that mod and could share it with me.
Any version would do, really. (Although the one before the addition of the fort's restoration would be the best for me)

Thank you for reading my request.

I thought it was http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=8268. Or are you looking for a different version?

I believe he made two mods. One that puts the Firemoth in an interior, and another one that expands the quest/fort.

Ah, I see, I mistakenly thought one had evolved into the other.

Oh! That's the one! Thank you.
