I have details of my ESO characters
here on my own site. Most of them are carried over from the single-player games, so their back-stories are long established elsewhere.
The "new" ones are Bo, and Laurie.
Since archery is a completely different thing in ESO than it was in the earlier games, being more of an AoE skill for close quarters, rather than the sneaky long-range single-target one from SKyrim and Oblivion, my archer is a new character. So she's called Bo, because bow.
Laurie Craft was supposed to be just a crafter, but she tanks, and the game allows that. The tanky build was good for gathering materials, where she'd get attacked while her back was turned, and she's developed into the full build.
They all wear a costume or outfit, so their appearance has no relation to their equipment choices. That's one feature of ESO that I particularly like. I forget what they look like in their armour.
