Ok I'm in Coastal Remains & I'm at the beach where on one side you go to find the turtle challenge. On the other side is a dark gem on a ledge. I can almost get to it by gliding from the ledge behind the seashell house. Its too low though. Also directly across from the ledge with the dark gem is a place where there was a dragon egg. Above that is a light gem. Can anyone please tell me how to get to these two items? Please help? Thanks!
