You can find the sage is right outside the place where you find a level 70 Volcarona. It will take a while though.
Relic castle catacombs( the place in desert resort)at level 70 at the door the sage was blocking. You have to find your way through the maze.
there is a backpacker in relic castle who will give you either a plume fossil (which is revived into an archen) or a cover fossil (which is revived into a tirtouga)
at the end of it
Volcarona is inside Relic Castle.
