Shadowscales are Argonians born under the sign of the Shadow, and taken by the Dark Brotherhood at birth to train as an assassin for the royal court of Argonia.
Yep, and if you played Oblivion, there is a DB sidequest where a genuine Argonian Shadowscale explains this bit of history. Unfortunately, the Oblivion Argonian Shadowscale's do not refer to you as Shadowscale even if you play an Argonian with the Shadow birthsign and join the DB.
Re the OP, I love playing Khajiit but am admittingly not all that up to speed about the lore. Probably because I don't like the Khajiit lore of being a slave race that much, so I don't pay attention to it. My Khajiit thinks that Khajiit, not Altmer, are the superior race because of their superior agility, stealth and nightvision. And he isn't about to let some poncy mage or egg headed historian tell him otherwise.
