Maze and Jess (Andusk)
From RocksfallWiki
Maze and Jess are twins in their early 60s. These siblings (Jess is the elder of the two, though only slightly) are the unofficial leaders of the human resistance. They seem to know everyone and every corner of the undercity, and most of the upper city as well, and their network extends even to the borders of Andusk. Together they plan raids to free human slaves, arrange for those who are willing and able to travel secretly to neighbouring human-dominated nations, and orchestrate other schemes of rebellion. They seem to have a weirdly co-dependent relationship (neither has ever married).
They are Andusk analogues of Maze Olivier and Jessamine Olivier.
