All the games are the same in a way, you play a evil overlord who controlls a bunch of minions(not the yellow ones but more like gremlins looking ones in diffrant colours and got speacial abbilities)
There are about 5 games, i know that overlord and overlord 2 got some treatments.
In the first game you play the overlord after 7 heroes beaten you and destroyt your tower, after taking over the first town and done enough evil deeds the towns people offer your there woman.
The first woman is seen tied betwin 2 poles(think king kong style) after the scene the woman runs away and can get captured.
I also found a early version of the game were they are sacrifices.
After beating many of the heroes you can capture the only female one, a desert thief named Jewel.
when captured her and returning to the tower she is shown in a cage.(This is the only scene with her captured)
The next treatment is in overlord 2, were years as past and you play the overlord son of the first game.
in these time a roman empire has rise that outlawed any magic and magic creature.
After taking over your own town and sailing for the next one the overlord finaly enters a jungle ruin.
There he witnes a trial of the roman woman Juno.
Juno is shown with her hands tied behind her back(no bounds are shown)
she get judge for seducing men but only is found guilty because a gnome walked under her dress.
After the trial she get draged away and the next time she is seen is is not tied anymore.
like i said there are more games but i dont know if there are treatments is there
