Elias ran breathlessly through the misty forest, no longer knowing what was dream and what was waking. Only a moment ago he was sitting in the library, staring at a leather-bound volume he had never seen before. The pages rustled under his fingers, the letters swirled, until suddenly - the world swirled with them. He woke up here, on the edge of Erithion forest, where the air smelled of rain and the promise of something unnamed. Scarlet leaves fell silently on the moss-covered path, and the moon seemed all too close, as if it was watching him with an unsettling attention. Elias adjusted his trim backpack and set off ahead, unsure if all this was really happening. He blinked as a silhouette flashed between the trees.

Suddenly the whole world sank into an ominous blue light. A figure emerged among the shadows - powerful, armed with glittering blades, with eyes shining like burning coals. Aila gave Elias a brief glance: - Decide, Elias. Either we hide or we face it. At the same moment, the echo of footsteps quieted, and light began to thicken around them, arranging itself into shapes Elias had never seen before....
