From D&D Wiki
Blashyyrk E6 is a campaign setting based on E6 with lower-power magic and a greater reliance on physical combat and practical skills. As such, there are many changes to the 3.5 D&D system to accommodate the higher reliance on mundane combat and changes to magic to offset the loss of its power.
This setting is an attempt to focus more on the character's own abilities and strategies, rather than relying solely on magical items and spells known. It should feel like Norse sagas, Conan stories, and other character-driven low magic worlds but without totally taking magic away.
 New rules for the setting
In order to get the necessary feel for the campaign world, many variant rules have been applied.
