"It makes sense now…" Zack thought while looking at the giant cube. "The more advanced a civilization becomes, the more they want to remove their physical limitations. It seems that this person managed to modify even the spirits of her own people to absorb them in case of a threat. Using them to power up this vessel and have the powers and resilience of who knows how many."
Zack kept moving around while thinking about what he should do. Retreating seemed like the best option, and then planning after confirming a few things. It was unlikely that the enemy would allow him to do so, but any time bought would be welcome.
