The Circle is... not quite solid, but solid enough, and provides an incongruous amount of traction.
It doesn't transport them immediately. Eelesia has to center herself and then use the Circle as the firmament of and fulcrum for the mana pattern she emits from her own body.
Navigation will, of course, be handled by her Intelligent Device. "Destination: Traceback."
Soaring Anima responds in a synthetic feminine voice, DIMENSIONAL TRANSFER.
And now they're somewhere else.
A cavernous space, big enough to hold the detailed holographic map of all nine of the primary dimensionally linked Childas and surrounding star systems at something close to accurate scale. A smooth, mirror-finish floor extends into the distance in every direction. Every hundred feet or so, large, lit-up work areas are sunken into the floor. Each pit is as large as some apartments, ringed by sofa-like seating, and contains a center of holographic screens, desks, chairs, a break area, and a meeting area.
Eelesia's is much like the countless others spaced across this vast chamber. She steps off the Circle and down the handful of steps, beckoning Verity and Araeneve towards the console at the center. As soon as they follow her, the Circle disassembles itself, scattering into motes of purple light.
