I wanted to do this my way, and not just destroy them technologically like the federation does. So I used demon magic via my infernal kingdom and started researching via the demon library how to handle them. Then I expanded into a new space, created a magic form for handling them and started planning a labour camp for hole people, where I'll force them to work off their debts instead, for maximum humiliation. They shouldn't think they get to escape this by just being executed in a federation gas chamber.
I created a DNA profile for a "slime dragon" and summoned one for being the organizer at the camp, then hired demons from a neighbour to do the footwork. I created armour and weapons for them and shared the magic for subduing hole people. Then the camp start being operational.
I then looked closer at the federation "destruction chamber" and realized it's actually the same thing, it extracts repayment directly from the hole people through gravital or magnetic forces, so what I created just does the same thing by manually using demon methods instead.
