It's better to kill him since you will get a nice heavy armor as a reward.

Well I've met the looters, but including the stash in their camp, I've found no quest item or whatsoever. Where did you find the quest item?

Have you convinced Icantha to pass on her legacy to you properly? If you have, normally Aldhelm will attack you on your second encounter since he's incapable to maintain his sanity anymore. At least thats what happened to me.

You need to bring Aloth with you when you're doing "Never Far from the Queen" main quest in the catacombs, after you come out of the tunnel, Aloth will apologize for freaking out inside the catacombs. Its after all those events that his quest is started.

What items did you get from killing Kolsc ? If I remember correctly, Raedric had a nice two handed sword

If you are not a cipher, you can just let grieving mother tag along, and she would wipe her memory.

There are 4 of them, 3 of which you need to find, the quest giver has the last one.

Does anyone know what to do/find in Cliaban Rilaq to complete this step ?
