As other people have said, you've listed them all, but the true ending isn't going to be part of the endings for HC3.
Hey, thank you for the kind words~ Really happy you like the game!
For the Discord server, I've been asked before, but the main issues are that it takes a lot of time to manage, which I'd rather spend on working on the game. Besides, it certainly wouldn't help with my already pretty limited attention spam^^
On top of that, from what I've heard from other dev, Discord servers either end up dead pretty fast or a place to simply exchange memes with each other, so not necessarily something that might be worth the amount of time put into it. Also, there's all the scam DM's you get from "promoters".
Thanks again for the kind message : )
Haylen and Lily have several reasons, which mainly boil down to one thing for each: maternal instinct and inferiority complex.
Haylen first wants to care of the seemingly trouble Jazon due to a traumatic event of her past, not fully revealed yet. Then, Jazon started sowing the seeds (hehe) of emancipation by trying to stir her away from her role as a responsible and lovable mother to reconcile her with her womanly side, the one yearning for passion and (sexual) adventures. Now, hes pushing the idea of Haylen finally bearing her own baby with him as her children are growing older and straying away from her.
For Lily, she comes from a race called the ailins that's been enslaved for centuries, and has developed a mentality of "being content with what you have" as a result, even after they were freed. Not able to bear with it, and wanting to raise above her condition and show that ailins are more than just former slaves, she embarked towards Nos'Ra.
Then, it's mostly Nezar exploiting her complex of inferiority and her desire to not be left behind to get her to do what he wants by promising her education and better opportunities.
Already in the game files.
