I saw a flash of light above us, and spotted Purity in the air high above the rooftop, using her power to create a flare of light, extinguish it, then create it again.
Hah! I see how it is. Who needs a flashlight for signalling when you’ve got Purity over here?
There was an answering series of flashes from across the water. It was a different set of signals than the ones she’d set up with us. It made sense for the light signals to be different from group to group, so Purity could keep track of who was coming and where from.
Yeah, sounds about right. And if someone uninvited observes from the shores and tries to use the same signal as someone they saw go through the process, Purity will know something’s up.
The main reason we’d agreed on this meeting place were the seclusion it offered, and the fact that it was just hard enough to access that the Nine wouldn’t be able to approach without us knowing. Hopefully.
Shatterbird being the one exception. And her clothes are probably quite reflective, which in a bit of a problem for a stealthy arrival in the dark with someone who creates light on guard duty.
Theoretically, though? Shatterbird could probably take the entire group on top of a block of glass and fly them all across. The only thing stopping her would be a weight limit, and as far as we’ve seen, she doesn’t seem to have a particularly low one.
