The Collector made preparations to leave. It utilized Sapia to leave the specimen exactly as she had been, covering her corpse, closing her leather bag, and returning her to her original position. 

Notably, however, the Collector took the record crystal with it, for in doing so, it would ensure that even if the tinkerers found the corpse and the undead swordsman, they would lack significant context and thus have fewer ideas of how to investigate the undead threat approaching them.

This would soften the tinkerers' military might greatly while the Collector traveled beyond the Rift where it would be untouchable to them. Then, when the Collector emerged from the Rift with another Shard and more military might, it could more easily engage a weakened tinkering force. 

There were of course ramifications for this situation regarding the conquering force the Collector had left behind beneath the Rift.
