It’s homebrew setting NPC time!
Malena Kitrova Grigorescu (later Malena Odinsdotter) is the former incarnation/title-holder of Loki, Norse deity of mischief, having renounced to her position to try and lead a normal life. Even by her own abilities Malena is a very powerful wizard privy to many forms of arcane methods and secrets, but she suffers from a very short attention span, constantly shifting interests and a laundry list of indiosyncrasies that make her rather unreliable and prone to generate problems rather than solutions.
Malena is at her core very introverted, but is also socially inexperienced and has a hard time accepting her introversion. As a result she frequently tries the best she can to adapt and succeed in social situations, much to her constant misfortune. She envies her surrogate sister Freyja’s extroversion and self-confidence, but also yearns for her affection and approval as much as she does her surrogate father’s (Odin), which puts both of them at odds the most from all of the Asgardian children.
