"All of the caves?" Mercurius widened his eyes slightly, then grew thoughtful. That was quite a few — he wasn't sure how familiar he was with many of them other than Eridanus and Orion. "Yes, yes, get comfortable, Arsu, there is some number of caves and stories that they tell." The storyteller, himself, settled down further, nearly flopping onto his side and sprawling out. A deep breath rose from his chest, and he began from the Core with a burst of magicka:
"Polaris is the heart of these caves, full of crystals and life. At its center lies a great spire, formed of shimmering blue stone and humming with so much magicka — you see, it is believed to be the source of all magic in the caves and the conduit which we receive it. A long time ago, before myself, even, there was a great black dragon who sought to claim the Spire as his own. Quite a few Gembound gathered to fight him, but they were ultimately aided by a great bird of ice — which I will elaborate on in just a moment. A river whose bed shines with the light of a thousand crystals cuts through all of Polaris, originating from a broken old dam and feeding strength to a wheel which is attached to an odd box. It is the source of all light in the caves, if I remember correctly. I don't know how it actually works."
"From Polaris, there are tunnels leading all over the caves. One of these tunnels lead to the waterfalls, Pisces. At the foot of its greatest rapids lies a glimmering, icy pond that is frozen at the bottom. This is due to the magical influence of the bird that fended off the dragon, who lies there in sleep. His name is Tenzin, and he is far older than all of us. If approached, you may be able to receive knowledge of the caves; yet, some of the ancient ones may lie. You have to decide what to believe and what you do not. Of to the edges of Pisces are moss-covered stones that may serve as shelter. Watch your step, there, since the rocks seem to always be slick. Even paws have a hard time finding footholds."
"Another tunnel leads to a room of mists called Cetus. All along its grounds lies a deep old swamp which houses a great serpentine creature — Aquarian, I believe — that seeks simply to survive. He is among the old ones, too. His Children, all adoptive, leave piles of food as offerings to him, so be wary if you find one. All around the swamp are many trees — they aren't like Eridanus's, their leaves are many and sharp. Their bark is hard as stone. Great stone spines rise from the swamp, nearly as tall as the Divine, which is the largest tree, possibly rooted to the bottom of mire itself."
"The tunnel leading to Pisces leads to another, called Fornax. It is regarded as the Great Furnace. Like Eridanus, it is warm. The majority of it is deep water, far too deep for either of us to swim to its bottom and come back up to the surface in one breath. Islands dot the surface, curving from the stones. Vents line the bottom of the furnace, bringing it heat. I do not know much about Fornax, though."
Mercurius paused for a moment, taking a breather. He began once more. "From Orion, there are two caves. One is a vault of bones, belonging to many and to none. Its farthest wall is marked with many drawings and writings, none of which we can read, I believe. Odd footprints circle enormous stones and fortresses rise above the landscape. Just at the edge of the stones lies a ledge. From this ledge, a great bird I only know as the Bone King spoke. I do not know if he is still around — I only ever met his son."
"The other room — and the last that I know of — is full of howling wind. It is known as Monoceros and is known for the twister at its heart and its gorge. Be wary of gusts that may sweep you off your feet, should you visit. An old group used to preside there, full of thieves and crooks. Now, there is only a blacksmith and a great dragon at its roof. If Dread approaches, be careful and be clear. Defend yourself if you must, and do not approach his treasures. He's very protective of them, or so I've heard. The blacksmith is named Glory, if I remember correctly, and presides in an enormous forge."
As Mercurius spoke, he hoped that his dancing lights would take the forms he desired, that they would properly represent each cave and tunnel's transition in accuracy. Moonlit eyes regarded his son carefully, watching for that avid curiosity that seemed to mark his demeanor. "Each and every cave is full of secrets and stories to tell, just as every Gembound is," the storyteller rumbled, tail swaying across the mosses, "all you have to do is be curious and explore."
