Floating in the void, icy darkness, turning its tiny solar panels to gain some energy from the faint sun in the vast distance the drone seemed inoperative. But once in a wihle, a beacon signal was sent like an SOS signal of ships of a long gone time on high seas.
3 more signals - the wise AI knew that the energy envelope will then exhaust and the once proud Warrior will join the dark matter of the space debris and tick its last CPU clock.
If it was human, it would be sadness. AIs don't feel this, but when checking its log record during CRC verifications, the entries created during in the drone bay of its mothership Nereus were accessed a nanosecond longer. Those were the good days, energy always abundant and also playing combat simulations with the fellow drones was possible.
But then a spaceship with the callsign Drones4Sale has popped out of the nowhere, extended its scoop and put the soon-to-be piece of space trash in its cargo bay. Thats me, the wandering drone collector, saviour of abandoned space drones.
Feel free to ask for drones, recovery of lost assets, salvage or logistics missions.
