My Redguard, Darius, has probably been my favourite character to play.
I figured since Cyrus the Redguard, a famous hero in Hammerfell, whether intentionally or not, was named after a great Persian king, I'd do the same. Also, I thought it sounded cool.
He grew up in Stros M'Kai, as the eldest of two. With Hammerfell in ruins as a result of the war with the Aldmeri Dominion, life was never easy for him or for his family. The need for money, combined with his own dream of exploring Tamriel, led him to take a post with the Alik'r in Skyrim, against his parents' wishes, being assigned to search for the fugitive Iman.
No sooner had he arrived in Skyrim, he deserted, travelling to Markarth in hopes of finding his fortune. What he found instead was a conspiracy involving the Forsworn that left a bad taste in his mouth when all was said and done. However, while in Markarth, he discovered an unusual gem that he determined would lead him to his fortune, and he consequently set out for Riften in search of an appraiser, eventually joining the Thieves Guild.
Discovered that he was Dragonborn, and slew Alduin. Joined the Stormcloaks (not that he cared about Talos, he hated the Thalmor) and the Dawnguard (Vampires being bad for business and all). Also completed the Dragonborn dlc.
