Taking to the sky on the elven wind glider was a spectacular feeling. Compared to the other beasts that the group had flown with, they were too in awe of this wind energy control.
From what Clark could guess, there was a lot of learning when it came to the beasts that Ella and Grace had. They had a good ability to learn from the unique uses of wind energy that the elven win glider was acting on. Especially since they were entirely protected from any buffering of wind at all.
This was due to the unique way the feathers of the elven wind glider were pushing away the wind that would stream around it. That allowed it to better slip through the sky regardless of the ways the wind and air put pressure on it.
