Yup, you got Age of Dusk ending and true ending, third one is that Esbeth gets out of dungeon but "darkness may come back" (it's sane picture as Esbeth in common clothes) and the easiest one is just at the start of the game go to the exit of dungeon while not finding idol and just running away.
There is one with sword and I found another one in game files named marriage. I dunno how to get both of them tho.
