Charon took them across the river, and as they stepped off the boat, he reached out and touched their foreheads.
Suddenly, Arin was back in his childhood home, playing with his siblings. Liana was in her grandmother's kitchen, learning the secrets of magic. Jax was in a dark alley, stealing a valuable jewel from a rich merchant.
The memories were so real, so vivid, that they felt like they were actually happening. But Arin, Liana, and Jax knew that they were just memories, and that they had to let them go.
They reached out and touched Charon's hand, and the memories were gone, replaced by a sense of loss and longing.
"We have paid the price," Arin said, his voice firm. "Now, take us to the source of the darkness."
Charon nodded, and led them deeper into the Underworld.
