From their position, crouching at the base of an old rock fall, they could detect no movement, thermal presence or any sound coming from the cave.Alex went alone to stand in the enormous mouth of the ancient cave. The primitive smell of the tunnel ahead threatened to overwhelm him, and though he couldn’t discern any threats to his team, he found it difficult to take another step forward. He’d lost an entire team of HAWCs in a cold dark maze below the Antarctic and it still haunted his dreams. He’d never suffered from claustrophobia before, but the idea of entering another cave system was making him feel tense and uneasy.Alex shook his head as if throwing off beads of cold water, then took one step, and another. Limestone coolness flowed from the tunnel’s depths and he knew there must be a vast labyrinth deep in the mountain. He stopped and marvelled at the giant statue standing guard at the entrance: a colossal, scowling warrior holding a sword as tall as a man.Adira came and stood beside him.
