I intended to play MW until I had done every possible quest twice. I will shortly have completed this. However there are three groups of quests I have never done and wondered whether there was anything special about them that I ought to try in my last couple of games.

One group is slaying the Telvanni Councillors for Trebonius and a second the disposal of the Thieves' Guild members for Sjoring Hard-Heart. I have a target spell that enables me to get anyone to attack me, avoiding others weighing in and the problem of bounty. I can dispose of Gaenor with ease. Is there anything interesting in these slayings or can I just assume they will be easy?

The other group is the 'back way' of completing the main quest using Kagrenac's plan books etc. I already clear out all the Dwemer sites in Red Mountain. Again is there anything of particular interest in this group of quests?

I appreciate that 'interest' is only an opinion but that is what I am seeking.

1) The Telvanni heads have a pretty strong security force, but nothing you should be worried about if you can clear out a standard Daedric shrine without much help. You'll get Trebonius's staff and amulet as a reward.

2) Nothing out of the ordinary -- it's an experience you can easily do without.

3) Let's just say that the jury-rigged Wraithguard packs quite a punch -- you'll lose 200 health for the duration of the game. If you have 1000 health before equipping it, you will be reduced to a maximum of 800 health afterwards.

To my knowledge, there are not any interesting and well-supported alternative paths to those quests -- I think that is because they are considered to be alternative paths in themselves.
