The Avatars walking up the mountain while bringing something valuable.
The Fiebending Masters:
Sun Warrior Chief: If you’re going to see the masters, you must bring them a piece of the eternal flame. This fire is the very first one. It was given to Man by the dragons. We have kept it going for thousands of years.
A New Spiritual Age:
Iroh: Sometimes, the best way to solve your own problems is to help someone else. This little fellow needs to go home as well. Maybe if you help him find his friends, you will be able to find yours.
