Sacred Haven of Debauchery

What is this? I can't figure it out :3

It's a mod like that. There are two options - Castle and 1. The beginning is the same, and only a bat is available for hire, and then the differences begin. After hiring, you are given a choice of units (determined randomly, they can give you a dragon or a peasant, the price is accordingly), in the first case, the number of units is equal to the number of "slots" in the castle (with the exception of the shelter), and in the second, only one unit is given for hire. After the unit is purchased, it is replaced by another random one.

Oh yes, "Era of High Magic" is also good.
