Marriage is usually an "early ending" option if you give birth to a baby from one of the few possible "fathers" in the game (still need to add a few more people to the list).is there any romance, marriage, with men? if so do you have a save please ?
Here are the possible characters/events to get pregnant (assuming you activate the option by visiting the temple of Santhora). Not all the options can lead to a marriage (and you'll probably understand why when you see the list) but almost all of them give you the option for an "early retirement". The one exception are the slimes, and any other monsters I might add in the future without any particular intellect or society, as they simply wouldn't make sense for a "retirement ending" to me:
Brothel work;
Nightly orgy at the bathhouse;
Clark, the baker;
The drunken guy (random encounter if you use Tarkas fast travel at night);
Lucas in Solina (only available if you are a bimbo);
The other drunken guy outside of the pub (only if you have Marintas's charm);
Chief Neroma (Minotaur village);
Slimes in the forest;
Drunken sailor at the inn;
Ronald, cheating husband;
Mr. Geralt, Secretary job;
Jiro, Alpha werewolf;
Nelson, Solina pawnshop.
The Emperor can't get you pregnant in game, but if you do his events properly you can join his harem and get a slide mentioning how in the future you'll become the empress during the ending.
