Strictly speaking, you're not allowed to base spec on information derived from decrypting the game files, although I think we basically allow variables and switches because they're so ubiquitous on the wiki at this point.
My read on the endgame goddess scrimmage (based on the variables and borrowing from Fulminato) is as follows:
The Mother and Mithyn aren't going to make it out alive, and their shards will get divided amongst the harem. Mestan is going to turn the tables on Lilith and absorb her, but find himself permanently ""Ranmaed"" in the process, removing the primary obstacle to his admission to the harem. That leaves two goddesses and two slots. (I'm reasonably sure the missing slot for Elleani in Leaders or Non-Combat is an oversight.)
Zelica is probably still alive. Remember that Mithyn used the words "that monster who has Zelica", present tense. Remember also the critical omission of any mention of the goddesses in the Anak's breakdown of the powers that be in Ch. 4, and the references to ""theoson extraction"" and the Anak "studying theology", plus Xestris' refusal to discuss their research into divine shards. Goddesses and the Anak's relation to them are the one thing he feels the need to actively conceal from Simon, ergo he's doing something related to goddesses that Simon would not approve of. Zelica is alive, his prisoner and a guinea pig.
So the final three (sans Elleani) are going to be Mestan/Lilith, Ivala, and one of the remaining goddesses, and I think Zelica is a better bet than Mithyn or the Mother, but Mithyn's odds are FAR netter than the mother.
