Wess was part of a group of Tempest crew members, led by Hela, who were plotting to kill Kallor (also referred to as 'the stranger') - a passenger of the ship who, along with his minion, Lars Jindrift - was sailing on the Tempest from Seven Ruins Island westward. Wess and the other corsairs were motivated not only by the wealth that it was evident that Kallor possessed, but also because they wanted to cut short the westward voyage across the ocean. Wess, pointing out that Kallor always wore a mail coat, told the quartermaster, Gudun, to open the ship's armoury and to arm everyone with crossbows and bolts. Unfortunately for Wess and the others, Lars Jindrift had been spying on the conspirators, and - hearing their plan - rushed to inform Kallor of the fate that the corsair crew had planned for him. Kallor had no difficult dealing with the would-be murderers, however, killing all but twenty of the crew, including - presumably - all of the crossbow-armed plotters.
- "Why sail onward?... He's one man, and rich! Let's toss him overboard and be on our way!"
- ―The corsair, Hela, addressing conspirators amongst the crew of the Tempest about doing away with Kallor.
- "West, he says... Like it's a stroll across the Deep... I say we get rid a' him."
