A hero with an army.

By the way, I recently encountered a situation where my liches, right before an attack, received something like an antimoral buff! For a second, a cloud with lightning appeared above the unit, which usually appears after visiting already looted pyramids! I'm seeing this for the first time. This happened right after visiting a pyramid.
Another time, right before the castle, in the sands, I found the Shield of Anduran on a corpse (skeleton). It was fun.
