These guys sound like they would have definitely kept up the
Rhuax_Pact.
Perhaps some of the
Magma Children have:
- Acquired sentience (no longer mindless) - good fire mages, or maybe heroes?
- Interbred with the pale ones (it's magic, don't think about it too hard) - this could explain the new fire resistance.
- Built up a standing population (perhaps sacred recruitables?)
- They like the heat, so they thrive (advanced summons with size/stats > magma children)
