I don’t think it was Exos. The pyramid ships have interior hallways, doors and lights. Landing pads. Things you would never build unless you planned on having people in them. Oh wait, wasn’t there an entry about Darkness possessing dead bodies one? In the BoS there was the implication of more then one Traveler. Perhaps a by product of the multiple timelines? Or could a gifted person grow enough to claim the title? As for TTK, I wouldn’t rely on it for the Darkness entity itself. Considering at base D2 they didn’t know what it was. So to me, that means that they aren’t going off the preexisting lore. It could have changed. Never know. Another is that the Pyramids are paracausal [i]beings[/i] like the Traveler. So there are entities on each ship and there are quite a few of them. Well the TTK lore there was never any mention of a fleet or multiple higher beings. “The Darkness” was mentioned attacking a fortress world while the Hive watched. The lore now has shown that power can be taken, gods can be caged and defeated and if Ghauls Light-body is anything to go by? Mantled.
