From the looks of it, it's not just that most of her content is buggy, reliant on random chance and restricted to players who do the 'go undercover by killing lots of allies for no reason' route, but datamining is showing , ALOT , of cut content, presumable voice acted and just not implemented.

is maybe the most interesting because it has implications about the games timeline? even though it's sort of weird that the most lesbian coded character, who her whole plot being revenge on her ex lover, had the pregnancy plotline it's still, at one point in development they had major content for her that's just... turned to smoke and blown away by release?

But stuff like this makes the demand she be included in not killing the grove playthroughs and fleshed out with more content stronger as it suggests most of the work/time/cost towards making her a full companion is already done!

Minthara is the best character and she NEEDS to be recruitable if you side with the grove!
