Duncan, since the red-purple abhuman was apparently implanted with the antenna to direct others, you could likely use it for the same purpose, or also, if another person had one of their own, to communicate mentally. Its "rootlets" lazily strain towards your implants as you hold it in your hand.
Echo, as you take it, the rootlets wriggle slightly against your skin, like they're trying to find a place to latch on to.
Antor, as you look down the hatch, you're met with a strong uprush of air. You can see straight down to the floor below, with no platform or other impediment in the way. It seems as if this might be your way down - the air itself. It seems like it should, in theory, lower you to the ground a good sixty feet below without harm. You can't see a great deal of the room from this angle, but you can see part of what looks like a shallow river of clear liquid, some very strong light sources at one end of the room, and smell a strong scent of earth, salt, and a metallic tang that is reminiscent of blood.

"There has been an access of the core. Access to the core was compromised by your initial entrance and not realized until now. We are not in a cycle-stage to store the intruder like we did with you. Assist the cycle and stop unauthorized core access. Assist the Keyholder. You will not be stored again."
