The Riphorn Tribe holds no allegiance to the ruinous powers of rot, and began moving east once the scent of death began to fill the air over Felde. Caught between the armies of both Chaos and Empire, some among the tribe have begun to believe they may be better leaders than Roargash.
Urgu Redhorn is one such Wargore, and he has initiated a leadership Challenge. The rules are simple: kill or be killed. Those who are not strong enough to emerge victorious become meat to feed the tribe.
Approach a set of skulls on sticks (with some skeletons on the ground) to the east of the main destruction road at 64k, 49k in Troll Country.
This tome unlock contributes to the Riphorn Challenge Exploration Achievement.
