Raen glided through the closed wooden door. Carina reached for the nearest torch and took it down from the sconce on the wall. No footprints except for the scrabbling of mice marked the dust-covered floor. It was cold, and Carina shivered. "How far?"
Raen beckoned for her to follow. They passed a row of long-abandoned bedrooms. The corridor smelled musty, as if water had gotten in. At the end of the hallway a stairway descended into darkness.
"This is the East wing, isn't it?" Carina said, looking from the ghost to the dark stairs. "It's dangerous down there-Jonmarc said that's where the walls collapsed when the orb was stolen."
Raen reached out an insubstantial hand to lead the way. Carina pulled back. "We should wait. I don't think this is a good idea."
Raen moved back into the hallway, where a thin shaft of light struggled through a dirty window. The dust on the floor began to move. This time, the ghost drew a bare-limbed tree, and beneath it, one word. "Understand."
Carina looked at Raen. "The power that touched me last night, the presence that's making it hard for me to heal-that's what you want me to understand?"
Raen nodded.
Carina weighed her fear against the frustration of her gradually waning power. "Can I reach the bottom safely? You can go through solid rock, but I can't."
Raen moved toward the door. As they started down the stairs, Raen's form began to glow, adding to the torchlight in the lightless stairway. From the cramped turns and narrow tread, Carina guessed that it was a servant's passageway. She grimaced as cobwebs brushed her face. No one but the spirits had passed this way in many years. Carina counted the steps as they descended, making note of the landings. They kept going, as the stairway grew colder and the air damp. Carina was quite sure they were beneath the ground. Finally, they stopped in an antechamber. By the torchlight, Carina could see that deep cracks ran through the stone walls. Through the next archway, the darkness was broken by a silver glow. Carefully picking her way through bits of fallen rock, Carina realized that the archway was the opening to a natural cave.
Raen walked beside her as Carina crossed through the archway. Inside the cave, large pieces of rock littered the pathway. The walls glistened with crystals, and in the distance, Carina could hear falling water. A doorway on the opposite side of the chamber had collapsed. Coruscating light filled the cave, surrounding them with an evanescent glow.
Once before, during an Eastmark winter, Carina had glimpsed the Spirit Lights in the cold night sky. The ribbon of colored light glistened yellow and green, painted in bold strokes across the darkness. Like the Spirit Lights, the glow that filled the cave changed colors, as if the air were filled with diamond dust. The walls shone as the light hit crystals, reflecting in millions of tiny facets.
