His past is catching up with him
Tiboth escaped the monastic discipline of Chen-Strary, called towards the mainland by an unknown force. To evade the Elders seeking to return him, he takes a circuitous route around the many islands. Adding months to his journey and resulting in a shipwreck.
He washes ashore on the island of Deerhold where a man named Aodhan takes him in and treats him like family. But the Elders of Chen-Strary aren't willing to let him leave them without a struggle. If Tiboth doesn't face his past, the Aodhan and his family will be the ones to pay the price.
