Dragon Cove

The name states whats in it. Dragons. The cave is located on an island in the sea. It's well protected and gigantic. It is separated into many parts and tunnels. Each part is different, for the different typed of dragons. The entrance appears as though the whole cave would be an ice cave because it's well....ice. But as you go deeper you'll find that tunnels lead into electrical areas, where electrical currents run through the walls, hot fire areas and normal cave-like areas. One main tunnel, however, can only be found by the purest of hearts and is rumored to be able to lead people into other realms, eras, etc. The cave can be found in both places, but only in Inuyasha's time may dragons be found.
