Catch my breath. Heh. Good one, Sky thought to himself, returning to him gaseous form to regain energy. Watching Draco run back down into the cave, he was suddenly overcome with frustration and slammed his body into the ground, the equivalent of punching a wall, I suppose. "Come on. There must be something I can do to help them back down there." He growled to himself, scanning his memory for some sort of way to get underground without loosing all of his power. "Ten thousand years. Someone must have told me, or I must have done it at some point." Sky was speaking to himself at this point, and honestly, it was lucky he had no mind to loose sanity from. If he had any sort of human emotions, he would have gone insane long ago. As it was, it was simply a way to focus.
Then, out of the blue, a memory surfaced. Approximately six thousand years ago, trapped underground.... Sky, not the time for a flashback. He chided himself, then reformed and steadied himself, floating a few inches off the ground, then Sky gritted his teeth and held out his hands. Slowly, a small blue orb began to emerge from his chest (which, for stereotypes sake, is where he'd put his Core in his human body), and floated into his hands, taking on a more solid form until Sky was holding what looked like a light blue stone, around two inches in diameter, perfectly round and pulsing gently.
Sky dropped back down to the ground, and let out a sigh of relief, before stepping into the cave cautiously. After hitting the incline again, he clenched the stone in his hand, and felt the natural energy pulsing against his palm. Holding it up, he then [I have suddenly developed writer's block, please excuse me if the rest of the post is complete shit], focused on the power stored inside of the 'Stone', slowly shaping it into a weapon. His power worked a bit like water, resisting certain forms, so Sky just about let it take it's own shape, only helping it along sometimes.
Eventually, he had formed a strange weapon, with the shape of two disks next to each other, joining at his Core and glowing a shade of blue not unlike the sky. "Right. So, that worked. Now all I need to do is make sure I don't drop my Core, and I should be fine," he commented to himself, whilst inspecting his semi-physical weapon. Sky then ran down to the cavern where rest of his students were, and dashed forwards, ducking past the others and helping the creature with his fashion crisis by removing half of his tendrils at once, then retreated back to where his colleague was standing. "Hey. How's it going?" Sky asked casually
