Rogue’s Gallery: Mazrin Krail

Book of Ebon Tides

Rogue’s Gallery is a series dedicated to showing detailed NPCs at different CRs, useful as mentors, rivals, patrons, or just for colorful casting.

To celebrate the launch of Book of Ebon Tides, we’re featuring an NPC for use in (or around) the Shadow Realm. They also make a great way to personalize the adventures awaiting in Tales from the Shadows!

Mazrin Krail

Mazrin Krail was unpleasant while alive. His drow masters capitalized on his misanthropy by facilitating his research into toxins and necrobiology, in hopes of using his discoveries to annihilate their enemies. In particular they funded his development of a variety of fungal and bacterial plague-bearing agents that displayed the number of ways in which living flesh can desiccate and decay.

If anything, Mazrin’s death and subsequent apotheosis as a darakhul has further narrowed his worldview, while widening the ability of his new darakhul masters to strike at nearby communities of the living. Mazrin cares little about who he serves so long as they provide a steady stream of live test subjects.

Personality Trait: I perform a host of rituals throughout the day that I believe protect me from occult threats.
Ideal: Domination. With the power I will unearth, I will take my revenge on those who wronged me.
Bond: No theory, however unbelievable, is worth abandoning without investigation.
Flaw: There is no law or social convention I won’t break to achieve my goals.

  1. Like this, not often I see a progressive stat block for an NPC.

    Where’s the errata for Ebon Tides ? Spotted 3 maybe, the Bearfolk Ley Walker is mentioned but not in chapter 9. The other is minor errors
