D'you know who General Rathura is supposed to be? He's an adversary in the crossroads, and my Rook remarked that he was part of the Dread Wolf's army, I think? No idea how he got that idea/came to know that information. Did they appear previously?
hello! ◕‿◕ after defeating this enemy my Rook said "The armor on those undead looked familiar... Well, whoever they served, they're fighting for the gods now." On defeating this enemy Rook can also say "Those undead looked elven. And ancient." If your Rook said that, maybe Rook's comment (and level of knowledge) at that point changes/increases as their progression through another quest does? (my Rook encountered this enemy quite early on).
I don't think Rathera or at least their name has appeared previously in the series. we know at least from Felassan that General was a rank that existed in the Dread Wolf's forces in the past, and we can say that whoever they were, they were an ancient elf. in the area behind Rathera are a couple of the frozen tree people like you can see in Arlathan Forest. and the Memento you can pick up from the area, the Unspoken, is connected to Dirthamen.
there is also this info/lines from the datamines:
"I've seen their armor on old frescoes. They fought for General Rathera. One of Solas's allies."
"The insignia. Those were General Rathera's soldiers." "And the gods have raised them to stop us." "Right! I remember now. An old ally of the Dread Wolf. And now the gods are raising them to slow us down."
Edit: @dreadfutures mentioned in the notes that Bellara gave them the dialogue about recognizing them as an old ally of the Dread Wolf. I reloaded a save just now to kill Rathera again only with Bellara in my party this time and my Rook said "The armor on those undead looked familiar." Bellara replied "The insignia. Those were General Rathera's soldiers" and then my Rook said the "Right! I remember now. An old ally of the Dread Wolf. And now the gods are raising them to slow us down." line.
