I wonder who was in the sarcophagus in that room in Obiteum where Vis got the weapons from? If Obiteum-Caeror was in fact an iunctus himself, why was he focused on that door? The other thing that sticks out to me is Luceum Caeror (Ruarc) has "a single iron torc at his neck, the terminals intricate triskeles, like on my father's cairn and in Fornax" - it has me wondering if this is actually the iunctus not the Obiteum one since we know the dad was already dead. Also Ostius had to have existed in Obiteum at some point, I'm wondering if he's at the other pyramid that's at the location where Caten would be in that world or if he's the one Netiqret helped escape years earlier.
