Looking for a Death/Nazgul kind of character. Evil horseman with a sword in black robes... that kind of thing.

1. I need Shadowmere, so I need to join the DB. Any tips/suggestions? The wikia said you have to kill an innocent person, but I don't want to kill someone essential to any quests.
2. I need a black hood and black robes. Where can I get some at? I'd prefer them to be old and tattered looking.
3. My weapon will be a one-handed sword, and that's all, so no shields or 2H. Can I wield spells in my freehand?
4. I'm going to be looking for darkness kind of spells, like summoning undead and stuff (no fire, no water, nothing like that, just darkness).
5. Any tips/suggestions on this build?
6. What should my main skills be focused on?

1. kill a guard

2. loot Necromancers

3. you can always use spells no matter free hand or not

4. Restoration have Absorb Health and Absorb Magicka if you like "leech" svcking life type, Mysticism have Soul Trap in which in my opinion sound dark and evil enough, Illusion have Demoralize in which making people fear you but they will run away from you, alternatively Conjuration have Turn Undead for scare away Undeads, Destruction have Drain Life/Fatigue but i found that not too appealing since Restoration Absorb is more useful

5. nothing come to mind

6. Since you want summoning, Conjuration for sure, Blade, Block, Restoration if you want Absorb spells, Illusion if you want Demoralize, Destruction if you want Drain Life/Fatigue, really major skills is doesn't matter except for Destruction and Restoration because these are so slow to level up, other magic school are fast even as minor, just buy cheap spells and train with it.

A build?
Well you will need planning permission, some decent drainage and foundations.
Probably get some nice country stone - that always looks good.

Finally someone who knows what they're talking about. Niza must be on crack.
