Tahnarism is the ability to manipulate a portion of the Anti-Principle (the "force" present in Bukrai) to accomplish tasks. It is an attempt to introduce necromantic magic into Hârn that does not rely on the Morgathian Church and its pre-occupation with death.
There's another new addition to the page of Character Sheets & Profiles (this one called Retro Ivinian, by Erik Lindenius) so we're publishing this page yet again. There's also a new version of Daniel Petrone's PC Profile Generation package, and after correcting a problem, it's now available for download once more.
