The Midnight Sun is the creation of a Maralee Shadish, like their sibling Evalwyn and their twin brother Ylos Asol. Maralee's mad science obsessed with Shadow-Ena and her mistreatment of her creations are what gave them their strong dislike of slavery and mistreating subordinates. Ylos remembers them as "Osci Asol", his twin sister, but they have decided to shed that name and identity, in part in order to better protect their brother, but also in order to find an identity for themselves.
A Shadow-Walker with Arrash characteristics, and the current leader of both The Silver Underground as well as The Sterling Syndicate. A calm and calculated person with a voice that is both as smooth as melted butter and as threatening as the most ancient of dragons, the Midnight Sun is first and foremost interested in keeping the business of their syndicate going, and to keep the Silver Underground a safe haven for ne'er-do-wells from all over Liwilai. However, they also seem to have a strong interest in keeping certain people on the surface safe, for which they often hire adventurers with stronger moral compasses than themselves. Their title instills both fear and respect into all members of the argentian criminal underbelly, due to their long history as a leader who is both efficient and not afraid to silence those who go against them.
The Midnight Sun's past is a mystery to anyone but their closest confidants and allies, though they seem to be close to their right-hand man, Hrazurr the Strangler.
