Kotl Gem

The Kotl Gem is the key to opening the entrance to the lost city of Kotl in the valley of Eodon in  Savage Empire.

Description
The Avatar became aware of the Kotl Gem, when Oaxtepac, the shaman of the Nahuatla Tribe, told how it would open the entrance to the lost city. However, he added that it had been stolen by the Urali Tribe on one of their raids and thus was presumed lost.

In a twist of fate, Aiela showed the big gem that Darden had tried to buy her love with. It actually was the Kotl Gem and Oaxtepac advised the Avatar to keep and use it. The Avatar did so. Going to the northern end of the Great Mesa, the gem was put into the fitting socket. At noon the sun shone on it, and it opened the secret entrance to Kotl, allowing the group to descend into it.

Trivia

 * This gem is not to be confused with Kotl Crystals, which are for healing.
