Josmarin was a divining mage who sailed with the crew of The Redeemer; using his magical skills alongside a smokey sphere through which he predicted the weather. With this foreknowledge, he helped guide the ship away from storms.

One day, while his crew was sailing near Jaia, an eldritch being conjured a powerful storm that wrecked the Redeemer at the shores of the Grand Cleft. Those who survived seek shelter and survival in an old ghost town near the wrecking site.

Josmarin blames himself for the wreck and the deaths of his crew. He now seeks to right his wrongs by protecting the remaining survivors and seeking vengeance against the creature that attacked the ship.
