Grimoire Auldrunis

The Grimoire Auldrunis (also spelled Aldrunis) is a massive compendium of magical knowledge, compiled by Aldrune. Aside from the Livera Scientia, it is the largest known grimoire in all of Tragulus.

Background
It is not fully known why Aldrune created the Grimoire, but the most likely reason is as an aid to himself. According to Malore Skol, even Aldrune needed to put some of his knowledge to paper, lest he forget it.

The few times that others gained possession of the Grimoire, they had to translate or decode most parts of it before it could be used; Koyaan Tcao said that it was "written in a manic mixture of Anglan, Elven and Vonychan, though each is fluent and masterful." This suggests that the book was not intended to be used by anyone else.

Content
The contents of the Grimoire Auldrunis are not fully known, but various evidence suggests that they include necromancy, sorcery and dark wizardry. At least one person is rumored to have prepared an apportation circle by following instructions in the Grimoire.

Anecdotal accounts speak of the book's power influencing those who handle it without proper knowledge, but this is uncertain.
