This guide will show you how to get each of the 3 endings. Not spoiling the endings, but assuming you have played through at least once and seen one of the endings, so you know what scene is being referenced.
So, not every choice in this game affects your route.
Your first set of questions is just for lore, when you first meet Vashtra. Choosing anything but “Hesitate” will give you some background, and return you to the list, minus that question. “Hesitate” will move you forward to the next scene and end your opportunity to ask questions, so start from the top if you care about lore. (‘Stay silent or ask for details’ ALSO apparently has no effect on anything.)
The second question also has no bearing on your route. Struggle or not, it makes no difference.
The THIRD choice, several in-game days later, is when your choices start to matter.
Twins Ending
To get the Best Ending, aka the Twins Ending, your choice of what to focus on here must be “your brother.” After that choice, you are locked in, gg.
You then have the Momentous Scene, and the choice to “keep the secret” or “confess”. This will affect who administers the Purification Ritual – the Patriarch will do so if you confess, or Gorian will do so if you hide it. Gorian’s scenes are much more /personally involved/, while the Patriarch at least keeps up a veneer of professionalism. (Personally, I found this section the most challenging to get through, even moreso than the Bad Ending. Choose wisely based on how much crying Seles you want to see…)
Note that there DOES appear to be a short missable scene featuring Llyr, which you get by choosing to “keep the secret,” and then much later, choose to “agree” with Gorian.
Either way, since you chose “your brother” earlier, both twins will recover and get their tails, and Seles will confess his doubts to Vel, and the twins will begin investigating, leading to the mysteries being uncovered, and then the Twins Ending.
Temple Ending
Second, the Temple Ending. You can either start over and find the ‘skip’ button, or go back to a previous save.
This time, you have to choose to be worried about “your priesthood”, which lore-wise fits in with choosing to dedicate yourself to the Temple. Then, after your Big Moment, choose to confess your sin to the Council. The Purification Ritual will go much smoother with him in charge instead of Gorian. The twins are allowed back into their rooms to wait out the 7 days. The Patriarch will declare them “purified” and their “fluids” non-poisonous.
Following that, you will be presented with the option to view an optional scene for the Insemination Ritual. There’s no CG and the writing for the scene itself is pretty uninterested and bland, so unless you really want Sel and Vel to have canonically bred a bunch of female “temple servants” there’s no compelling reason to watch it, imo.
Vashtra joins the twins on their pilgrimage to convert the whole kingdom. There’s a tiny choice, just after leaving the temple, of whether or not Vashtra submits to the ‘new authority’ or fights it. It does not change your ending, but you get a bit more humiliation for the twins if he backs down.
Then the rest of the Temple Ending plays out, (and it’s kind of depressing, actually) and only one more to go.
Bad Ending
For the Bad Ending, choose the “priesthood” as being more important than your brother. Then after your Big Moment, choose to “keep it a secret.”
You can, after the clandestine purification ritual, choose to ‘agree’ with Gorian, if you want Seles to see Llyr for one last time before the inevitable Bad End.
