Elvind
A mythical Norwegian character. Recognizable by their ginger hair and extremely pale skin they are generally unable to remain in the sun for longer than 20 minutes. As a result, they prefer nocturnal activities, typically bar hopping and clubbing. After evolving in isolation for centuries, the advent of international travel has exposed them to multiple new diseases that their unique immune systems have shown to be incapable of handling. In particular, the entire population is known to be infected with yellow fever.
Man, did you see that Elvind? I bet he's got yellow fever.
