Meanwhile, Arclight is doing stuff.
2 of the 4 lightdebts decloak, the 3rd and the 2nd. 3 colony ships come into view around the second lightdebt, as if made of fog, before looking decisively solid. They thrust towards the nearest ship, staying a sensibly safe distance away from its weapons, scanning for undetonated bombs and suchlike.
The third lightdebt decloaks with similarly unimaginative special effects, revealing 2 more colony ships, and 4 medium-size fighters with rather large thrusters on the back. The colony ships whirr before going and looking at the second nearest ship, in a similar way to the other 3.
Note: all these ships seem to be encrusted by traffic cones of various sizes.
