Sundered towers is right next to the end of the redoubt. Ive done this quest 4 times with respawns as it comes around again as part of the bounty quests in Markath. Its not just the cave, its the outside section as well which leads up to the leader's throne which is directly beside the Sundered Towers. And when you tag it in the quest log, you have to both tag the misc. menu AND the quest itself inside the menu before it will be tagged properly.
You Still think Im stupid

I have tagged Misc. I have tagged the Q.
There is no marker. Clairvoyance says "no active Q". ITS A BUG OK?
Now I need help fixing the bug.
But first I would like to find this leader and see what happens when i kill him.
Your directions doesnt help me at all.
Deepwood Redoubt is waaay north of Sundered Towers.
And when you enter Deepwood Redoubt you proceed east, into Hags End. Not south down to Sundered Towers.
Please give me PROPER directions.
And if he is in hags end, why does it say "kill the leader of deepwood redoubt" and not "kill the leader of hags end" as it is two seperate locations on the map, with two seperate "Cleared"-mechanics.
I suspect neither of you really know where he is - . -
