Portal of Rage

So many of the Blazing Sun have lost their way in here. In this unnatural brass obelisk, jutting out of this accursed mountainside. They have forgotten the strictures of Myrmidia. The weak became so consumed with defeating the enemies of humanity at all costs, that they became an enemy of humanity. Hold closely the strictures of Myrmidia when you ascend the steps to face the mightiest of daemons, lest you fall to the rage of Khorne. Meditate on them in every step of your journey. Find the source of the evil that brings this place into existence.

Ascend the Steps of Ruin. Use the Myrmidia Strictures in inventory on each of the steps in order.
