This mountain is shaped like a dragon's head with its mouth open and fangs are shaped. Once you land inside the mouth you enter through the throat and it will lead you to tunnels, many inside many outside. Outside there is a large open area with a lake in the middle of it and green soft grass and a few trees around it. All around it are several ledges which have many caves within them. These caves are for guests, they fit the guests habitat. For instance if there were a fire dragon the room would go down to a lower level and be very hot with mama rivers and so on. The lower level is also connected to the other caves and the dragon could go through them and visit with others if they so wished. The council members such as K'lant, the head of the council, prefers the outside so there are caves for each of them members to accomadate them as well, like the guests caves but a litte larger, especially if they are the ancient dragons who are much larger than the dragons today.
This is also where they hold councils that concern the world. The meeting room is large enough to fit every race of the world inside. It is black obsidian rock. And the higher platform is where the council is where as the guests are on the lower levels.
