“And you, TwinSoul?” Marasi asked. “Is there a limit to the things you can make?”

“Alas,” he said, nudging his backpack, which was on the floor, “there are indeed serious limits. I can only maintain roseite objects under certain fields of Investiture. Some planets have those naturally, but yours does not, so my roseite creations—outside of our safehouse—must be touching me, or they will disintegrate. It also requires water, drawn from my body, to fuel the creations.

“Beyond that, my ability to form objects is limited by my personal skill and understanding. I cannot make you a gun, for example. The mechanics are beyond this old mind, and the intricacies too fine. Simple tools are the extent of my abilities, though Silajana has bonded some more talented than I in that regard.”
