Operating Hyacinth

Half a month passed peacefully on Hyacinth and Zero's return took everyone by surprise. The lad hadn't sent word in advance and caused the servants in the sea temple to go into chaos after knowing that he was back. Instead of greeting his teacher first, Zero went to the place he created whirlpools and started working on the planet's infrastructure.

Fusing Gummer's weak planet core into Hyacinth's dead core was slightly trickier than Zero thought it would be. The dead core wasn't very receptive to life and even if the planet pulsed with the weak energy, it started to reject the foreign object less than an hour later. Zero was puzzled by the rejection and had to investigate further, delaying his return to the temple.

"We discovered spirit tracks in the planet's core," Mii reported and showed Zero the diagram that she drafted after a very painstakingly detailed scan with Wii's aid.
