A few NPCs may travel between Orn and other worlds during the course of the campaign. As noted in the Adventure of the Dragon's Scale, the unique nature of Orn raises a person's Constitution by 2, Intelligence by 1 and Dexterity by 1. These may affect hit points, saving throws, attacks and skills as appropriate.
All characteristics given here are for the Non-player character whilst on Orn. If they arrive on another world (eg the Ixixion-world) from Orn their characteristics are reduced by the same amounts, with the equivalent effects.
