Tree of Erisdar
The Tree of Erisdar is the main place where all the meeting are held by the High Council as well as tournaments between the different dragon races to see who will hold the Title of Fiercest Dragon. However no one has been able to defeat the current holder of the Title, Shalerth. Shalerth is part of the Council and specializes in combat training so it isn't strange that no one has been able to defeat him in the tournament yet. However in the lower level of the Tree is the Gateway used to travel back and forth between this Realm, the Human Realm, and others. It is one of the oldest trees to exist in this world and so it was made into the base of the dragon council and where all worldly events would be held since it sits exactly where each of the dragon territories connect. In other words, it sits in the center of the continent. It is said that a rare treasure is hidden in this tree but no one knows if this is true so they ignore this rumor, most do anyway.
