The long-dead, paranoid bugbear treasure hunter who sank a submarine into the tomb hunting the Gate of the Feral Gods.
Shamus Chaindrive was a great bugbear treasure hunter — paranoid and greedy, betrayed one too many times, so he crewed his expeditions only with constructs and automatons. He prized one treasure above all: the Gate of the Feral Gods, said to be buried in the Necropolis of Anser. Vowing never to surface until he had it, he sank his great submarine, the Akula, and spent nearly twenty years finding the tomb, docking against an underwater entrance beside its main chamber.
He found rivals already there — a young mage burrowing in, and a colony of Dirigible Gnomes settled nearby — and unleashed his greatest weapon, the stasis-stored sentinel Ruckus, to kill all competitors. Long dead now, Chaindrive left Ruckus circling the island until the day Carl's meddling seemingly reactivated its original kill-order.
A bugbear (long dead); no living description given, remembered only through his automatons and submarine.
The dead architect of the water quadrant's threats — the Akula submarine and the sentinel Ruckus — and an early seeker of the Gate.
