This is The Lamb and their first spouse in my playthrough, as well as their first follower, Lycoris, who I brought back to life briefly just so I could get a screenshot of what she looked like, haha. Anyway, I imagine these two loved and adored each other very much, and they were happy together, but their time was much too short. When she grew old, The Lamb performed the ritual to ascend Lycoris. I think it would've been hard for them to watch her slowly deteriorate, so perhaps they thought it was kinder, or they just didn't want to watch her die.

That's just based on what I actually did in my playthrough, though.

Either way, their short time together might be why when they married Andre, they chose to give him the skull necklace so that they could be with him for as long as possible. Unfortunately, things didn't work out that way..

In this picture, they're giving her the feather necklace as a gift. I also attempted to draw a red spider lily on her head because that's her namesake.
