In regards to something involving the main cast

[Theodric]

Don't forget that the "funeral" wasn't done for disposed creations, it was meant for promising experiments acidentally killed for no fault of their own, like in that specific case where they "mourned" a group of beings killed by a failed, over-agressive species, one that was to be put down with no fanfarre at all.
Rather than mourning the lives lost, it's more like they were bothered by their efforts spent being wasted

I think that's rather disingenuous framing given the numerous side quests showing that many of the Ancients throughout Elpis cared for their creations. Even in cases where Ancients believed the player character was little more than a familiar there's multiple examples of Ancients expressing concern about the player character's aether and even offering to fortify it.
