"Ebony armor is the third-best heavy armor, behind Dragonplate and Daedric armors. It appears in leveled lists starting at level 32 (enchanted varieties at level 33)."
I kind of need something to start off with......cause...I won't find ebony in a while.
Yes yes I know

But seeing as gear spawns are level dependent, you don't have many options.
Steel plate isn't dark, but the full helm might lend you a bit of mystery.
Honestly there aren't many armor choices without pc mods, so you just have to svck it up a bit until you hit ebony.
What's important to remember, though, is that the way you play and imagine the character is ultimately more important the armor he/she wears.
