We couldn’t activate any lights, of course. The cargo drone had the usual ice core to keep its heat signature down, but having the cargo bay open was doubtless interfering with that tactic. At the levels of sensitivity that such things operated under, even the small amount of infrared radiating from the dark side of the topopolis strand would be adding to our heat load. Our mannies weren’t heat sunk either, so we glowed like miniature stars in infrared. We had to make the traverse to the entry tunnel as quickly as possible. While it was unlikely that any Boojum would pick that exact moment to do a sweep, we were all firm believers in the power of Murphy.
