30 Warriors -- Freemen and Captives -- to populate your arenas.
30 cult members, of varying levels of sanity and skill. Divided into Guilds for convenience and clarity. Could potentially be used as 30 gang members, depending on your needs.
A man is arrested for mass murder and found to be insane. Piles of corpses were found on his property, neatly stacked torsos with the skin peeled off and the limbs removed. The man readily admits the work is his, though he claims he was only chopping down trees, removing their branches, debarking them, and then stacking them to season.
The man may have swung the axe but it was a Druid who caused the delusion. This Druid is still on the loose and likely to repeat the crime. In time he may get more creative in his "punishments."
