There was a flickering multicolored light around both his energy well and his mind palace.
For his energy well, the fusion with the natural wonder made it more solid. So his energy well stopped being an intangible object within the void at the center of his existence and became a physical object called a power core.
As for his Mind Palace, the changes were mostly caused by the colorful light of the natural wonder. The colorful light from the natural wonder diffused into his Mind Palace and spread throughout, touching everything in it.
