Felarais, my female high elf, she got booted out of shimmering isles, just because she killed a few people. Such an OTT reaction. And the stormcloaks are massively racist against altmer, so she's a sabateur against the 2 factions. Being an assassin, she doesn't normally go head-to-head, rather assassinate lone legion/stormcloaks, take out VIPs, disrupt executions, take out patrols and leave the tied up prisoner to their fate, et cetera.
Other than that, she never wears a helm, only sleeps in bedrolls or under the night sky, doesn't have any decorations in her house (used only for storage), and silent rolls everywhere. She will only wear stuff that looks elven, or something easily repaired by pelts (scaled armour, for example). If someone hires thugs to kill her after a bit of supply gathering, she will deal with the thugs one by one, get the bounty, and end the life of the hirer. Old woman who lives in Riverwood? She got what was coming, I only stole a bit of food.
And nothing is as enjoyable as silent rolling out of water and dual-dagger-sneak-power-attacking the target. I feel like I'm the equivalent of a spec-ops in Skyrim. And she never uses companions or horses. Okay, occasionally she'll use a horse for a short time. But anyone she passes she will kill to keep the secret. And then kill the horse and run off. No one will ever know.
