Grand Duke Lance's power was "throwing."
It wasn't a power fit for a Grand Duke. Usually, someone with this position would be expected to have some grand power that could control the laws of everything.
Lance was an outlier. He was born with something that didn't seem to have any use at all, but with his ambition as fuel, he worked and worked until he turned that talent into a goldmine.
Throwing was an incredibly tedious and repetitive power to train. Lance had to understand the movements of his body beyond anyone else, and he had to obtain the most perfect form to even reach the starting line.
Eventually, his power became massive.
Throwing was taken to a new level.
Anything Lance touched could be "thrown" as long as he pushed it with his arm. And as long as something was thrown, he could control it like his own limb.
