Malevanor—the Blood of Vol’s high priest of Atur—seems to have genuine faith and sits between Erandis, the Crimson Covenant, and the Seeker community. What makes him tick? Is he good, bad, or in between?
In life, Hass Malevanor was a Seeker priest and student of necromancy. A Karrnathi patriot, he devoted his life to helping to develop superior combat applications of necromancy. Along with Gyrnar Shult, Malevanor played a key role in the development of the Odakyr Rites—the rituals used to create Karrnathi Undead. The basic principles of the Blood of Vol maintain that the universe is cruel and that we must stand together; Hass fought for the good of both his people and his nation. Exploring Eberron says “The former high priest of Atur was the mummy Askalor, who held the post for over four hundred years—but he was weary of his long undead existence. When Malevanor was grievously injured during the Last War, Askalor transferred his power and his undead existence to his apprentice.” This ties to the point that Seeker undead—especially the Oathbound—are expected to guide and protect the living. As both High Priest and Oathbound, this is the role Malevanor sees for himself. It is his duty to guide and protect living Seekers. As an Oathbound, he can never truly find the Divinity Within—but he can help the living Seekers and seek to find and aid those who may yet be the greatest living champions of the faith.
I personally believe that Hass is still a patriot who loves the idea of Karrnath, but it’s also the case that Karrnath has betrayed him and his people. He will always put the good of the Seekers above all else—but if he CAN help Karrnath along the way, he will.
So in Kanon, what’s his relationship with Lady Illmarrow?
I think that Malevanor believes Illmarrow is dangerous and that he questions her devotion to the faith, but he also realizes her POWER, and both a) doesn’t want to have her as an enemy and b) wants to see that power used for the good of his people. So he’s trying to maintain an alliance with Illmarrow, but it’s an uneasy relationship. Ultimately, he is OATHBOUND. I believe that his oaths are just what it says on the tin: that he is bound to protect the Seekers, help them find the Divinity Within, and to maintain and protect Atur. Which is an interesting contrast with the lich Illmarrow. I don’t think Malevanor COULD betray the faith for his own personal gain, because the oaths that sustain his undead existence are predicated on doing his duties as high priest and protecting his people.
Could Malevanor be a warlock patron (say, Undead or Undying)?
Sure, Malevanor could definitely be a warlock patron for a Seeker warlock. I’d love to do a campaign with a PC Seeker warlock who’s essentially Malevanor’s undercover agent working against Illmarrow. The main thing I’d emphasize in this case is that it’s not that Malevanor is giving the warlock powers, it’s that the warlock’s powers come from their own Divinity Within and that maelvanor is just helping them to unlock those powers. Because that is literally what he’s supposed to do: help Seekers harness the power of the Divinity Within.
