Rossi Wulfgard introduction in Endfield

Rossi was just introduced in the story (member of the Wulfgard) and seems like she knows the Endmin since before the stasis and she idolizes her completely. Just how old is she? She looks in her teens, maybe 20 so it's likely she only heard stories from other people about Endmin.

I'm still a bit puzzled about the whole goal of the story so far, we're trying to expand the use of Originium in Talos-2, but that's exactly what Doctor from the first game was trying to avoid because of the consequences of using it (health related even if it seems they can mostly control the side effects in this world).
The Endmin lost his memories so we don't know the full details of his goals, but the two seems to be completely opposite. Many theories are surfacing online about the connections between Doctor and Endmin (alluding that Endmin might be connected with the villain of the original game), but nothing that is actually revealed in the story.
