We have a new gemlair built near Delgarath. Fyrethorne discovered it. Tsargoth handled tier 6. Siivyra handled tier 5. It's all built but needs the devs to be activated.
The only down side is unless you're an adult or ancient dragon, you can't get to it because you have to fly VERY high above the Demon Lair to find it. It's not viewable from the ground and none of us can figure out where it's SUPPOSED to be linked to the Demon Lair.
