The Tome of Endless Savagery is a unique Tome that is received as a reward for completing any of the "Test of Strength" Global Quests or the "Winter most Worrying" Global Quest. There is also a small chance to receive it as a reward for searching Unspoiled Ruins after reaching Era III.
Though this was originally written as a treatise condemning the worst excesses of war, the details it contains on the capture and destruction of Auriga's Guardians will be useful to those who must confront them.
