Knights of Ashok did only cost wage, when placed in the army of my sovereign. I had a total of 6, but paid only for the two which were part of the army of my sovereign
Orphidians lair (or how ever those snakes are named), spawned 3 sets of monsters: 3, 3 and finally 4. So a total of 10 orphidians.
I'am not sure if that is intended that way.
All other lairs just seem to spawn single "monsters"
