Claws of the Clouds Mountains

The Claws of the Clouds Mountains are a mountain range near the east coast of Pyrrhia. It is mentioned in The Dragonet Prophecy, the prologue of The Lost Heir, and The Dark Secret. This mountain range was where Starflight thought the dragonets' cave was, and his theory was eventually confirmed by Webs. The Claws of Clouds Mountains is part of the Sky Kingdom, where later in the first book, The Dragonet Prophecy, the dragonets get captured by Queen Scarlet.

Under The Mountain
This had been the cave where the dragonets of destiny were raised, the place that locked them away from the rest of the world. It was hidden under a mountain of the Sky Kingdom; more spesifically, The Claws of The Cloud Mountains, which the dragonets didn't know until Queen Scarlet came and held everyone hostage. The cave was probably destroyed when the SkyWing guards invaded the mountain.
Description
There were nothing but rocks that had no difference in texture; if it weren't for Glory's iridescence the dragonets would have never known how many colours existed beyond the boulders. Whenever Kestrel fired Clay during battle training he would climb on top of a stalagmite for momentary shelter from the intense flames. Clay used to think, "Why couldn't there just be a little mud down here?"
Water in the river had always been freezing, but it guided to all the caves under the mountain used for a variety of purposes. Scrolls were the only source of reading material, while the dragonets studied the map of Pyrrhia, occasionally trying to locate the cave. When Clay and Tsunami would eavesdrop on whatever the guardians were scheming; it wasn't long before they realized danger awaits behind the scenes.
