Whoosh!
Similar to the sensation he experienced back when Adam changed his body to that of his actual self, Valyr felt as if all of the strength in his body was being siphoned to some far-away place, making him think as if it was impossible for him to reclaim such strength in the future.
Though, by the time he felt like there was no strength in his body left, waves upon waves of strength began to course throughout his body all of a sudden, each wave carrying a flavor that he'd become more than familiar with over the past few years he was in Veldanyr.
While that was happening, the various parts making up his entire body began to shift into another form, allowing more strength to surge out from the depths of his body as he eventually took on an appearance that he thought he wouldn't be seeing in the near future.
