Then I thought maybe they’d be tied to a community puzzle or secret exotic quest, and that does not seem to be the case, given that we are literally now in the last week before next season. The original thought was that they were going to be tied to Vex Mythoclast or its catalyst. I have been through so many theories as to what these were supposed to be, but none of them have panned out.
When the season launched, a Vex conflux, floating oracles and a spawning Minotaur boss appeared in a few Tangled Shore Lost Sectors.
