I think that is all the main endings. (Let me know if you find another I forgot about writing, lol.) There are some other game ends, for the curious:
Two are epilogues showing glimpses of just how bad the problems with memory could get for the humans:
- In the Grove of Muses, if you reach it with less than 500 gold, you will probably have the option to flee. But this will end in the game epilogue "The Loss." This ending can also be reached by following the dream in the cave in Ashen Veldt.
- If you choose to work for Captain Brost and offer first aid, you'll eventually get an offer by a mage to work for him. This will lead to the epilogue, "Like Flowering Grass" if you accept.
Three death ends:
- Death is possible in the blood gauntlet, if you haven't been through enough 'horrific' events in game.
- If you choose to stay the last night in the Sand Rat Inn vs. returning to the merchant caravan, you will get the death scene "Circle of Fate"
- If you buy the wrong gift for the Empress (the derby hat) she will have you sentenced to be publically killed. I forgot to give it a nice title so it's just "the derby hat."
