2 UAVs sat in their hangers, awaiting orders. due to the raiders being after alien tech, the UAVs were ignored. completely. even though they had quite possibly the most exotic design ever.
so, during the raid, they remained in their hangers. their AI, gifted with sentience, became rather bored. an attack meant that they had to be turned on. but given it was a raid done by civilians, they had to remain hidden. eventually (and by that i mean 5 seconds into the raid), they came up with a game involving blockchain to pass the time.
so, here we are, present time, and they are still playing that game, trying to see who can acquire the most bitcoin. suddenly, Hugin stops.
<<There appears to be an intruder near us. literally. I can see it in my cameras>>
Munin also stops
<<what do we do?>>
<<unknown. making a request for orders>>
suddenly, Skynet receives a report. the 2 experimental UAVs have visually detected an intruder on radar. they are requesting orders. clearly they are bored.
