Aldrich wasn't fretting over nothing, it wasn't just the fall that could kill them. Giant eagles had variants at grade one too.
It was rare but still a very real possibility, if such a being attacked them from the air there would be nothing they could do.
Last time they happened on this flock of giant eagles hunting fish on the sea, their nest was probably somewhere on these cliffs.
Aldrich released his [Invisible Sword] and pointed at the eye of the giant eagle on the bridge. His meaning was clear, if anything happened you will die first.
No one else but Aldrich could see the sword created by pure Aurora and to everyone it looked like there was a stalemate.
A long moment later just when the time of the skill was about to run out, the giant eagle spread his wings and flew off of the ancient land bridge.
