After combing through some of the ghost scannable for clues recently as to why I may have finally located a scannable on Nessus with some answers. "A Conflux that’s directly connected to Mars. The Vex there are having a heck of a time with the Red Legion, it seems like. “Garden gate gone. Bay lost. Bastion fallen.” Huh." Garden Gate must mean the garden is sealed off from access. A defensive mechanism for sure unless the network deemed a more credible threat elsewhere and closed it off to focus troops elsewhere. Bay lost. This is an indication for six potential sites on Mars honestly, but I think the "bay" is the teleporter underground in the old subway station or the conflux which charged the gate eye. Both have respective "bays" and both are sites where the Vex contested strongly. Losing those ground would have significance, but the reason also for the transmission to Nessus- regroup on Nessus. Bastion fallen. That can only be the location right before the heart. The bastion of the black garden more specifically. One other thing: The vex knew the black garden and its corresponding bastion had the darkness to reconstruct those statues. So if the Cabal is pressing inwards like that at Calus' direction? Then we have the answer for the barge and menagerie potentially: Calus is reaching out to secure Vex installations in preparation for the oncoming war. We do not need time warping Cabal on the field. There is no escaping that. Es[ecially if they learn how to do it with those giant guns on the Leviathon. They won't need a fleet to destroy us if the darkness can suppress our capabilities. My best guess for the black garden now is the heart will try and restore itself and we must wrestle the control away from a faction which seeks its power while it is dormant and sealed away.
