Dee

The long-missing elder sister of Caligo, Dee was 6 years older than him, growing up in poverty alongside her brother.
When she was 19 and Caligo 13, she became involved with an unknown benefactor, and spoke to Caligo of a "pact" she had sworn. She was able to provide for the pair of them exceptionally well for nearly two years, before disappearing with barely a word. A message arriving to Caligo 7 years ago simply stated she was alive, and not to look for her.
