The kua-tin corporation running the crawl, which wants Carl kept in the game despite the danger to its solvency.
A representative of Borant listens in on Orren's meeting with Carl. Orren says Borant did not intervene at Larracos because they expected a different sort of attack and assumed Carl would lose access to the artifact afterward; they are upset, but Carl likely made them more money than they lost.
The kua-tin previously wanted to keep Carl when Orren would have had him removed, and they still do not want to take the easy and obvious route Orren favors — not yet. Orren pointedly raises his voice toward the unseen listeners when noting that Borant wishes Carl to remain in the game despite the danger he poses to their tenuous hold on solvency.
The corporation running Dungeon Crawler World, financially dependent on Carl's popularity.
