The maelstrom was a massive series of whirlpools, lightning storms and hurricane force assaults upon the Magna Hydrus. The whirlpool was so deep that it plunged to the very sea-bottom and beyond such that most fell to their doom.
Before the fateful crash on the reef, Marcus and Herran slipped their bonds and ventured topside.
Marcus, before he could offer help to the crew, was swept off the deck. He saw spirits of water and air battling within the Maelstrom and believed the storm to be no natural occurrence. He was lifted from the sea by a hand made of clouds and delivered to the island beach.
Herran, a true prisoner, escaped his cell by shapeshifting into a rat. In so doing he freed not only himelf, but the POW Atreides to whom he was tethered. Despite being so small Herran could not stand long on the pitching deck. Thrust into the depths, Herran found and transmuted himself into the form of a deep shark. On his way to shore he found Therondil unconscious in the water and delivered him to the shore.
Faraday, a halfling stow away hiding as part of the crew, released the prisoner Rath. Together they grabbed supplies and escaped in one of the small rafts. The raft was destroyed, but not before delivering them to the shore.
Leondras, a dwarven warrior of the wilds, burst his chains through main strength and attempted to save Naugrim, another dwarven prisoner who’d saved his life. By the time he broke him free, Naugrim had drowned, but Leondras carried him to shore, unwilling to let another dwarf lay in a watery grave. On shore, Naugrim revived as if by a miracle.
Ultimately the Magna Hydrus was hulled upon the island reefs. Few survived and most of its supplies were claimed by the depths, but some wreckage reached the shore. The aft section of the ship can be seen from shore, though the waves claw at the remnants, pulling it to join its doomed crew…
