I’ll probably never write this one, but for a dark “after ending ending for Xenogears” it popped into my mind, and so just posting it here as a plotbunny for anyone of interest.

(or if you want to take it really dark beyond what I’d even consider writing out in any detail beyond this, probably, Citan and/or Elly still live too, but as effectively pets as Id justifies controlling them as such as revenge for what Solaris once did to the planet…)
