The Court of Harvesters are a reputationfaction in Revendreth comprised of venthyr and their servants. The court is made up of the eponymous Harvesters; venthyr that were created or chosen from former mortals by Denathrius to represent certain sins to be used in the name of Revendreth. These seven harvesters were gifted with special medallions that gave them tremendous powers. After Denathrius' turn to the Jailer, elements of the court rose up in defiance. By the end of the [Venthyr Campaign], only the faction that rose against Denathrius survives, and more and more venthyr are binding themselves to the court instead of the Master and his tyrants.
After countless ages spent under the rule of Sire Denathrius, authority in Revendreth is now shared amongst the Court of Harvesters. These noble venthyr carry out the sacred duty of redeeming prideful souls.
The Court of Harvesters are those venthyr who bear the seven Medallions, called the Medallions of the Harvesters, created in Sinfall by Sire Denathrius, each containing a fraction of Denathrius' power, and allowing Denathrius to see the actions of each Harvester. The Medallions give each Harvester authority of their respective Ward and duties otherwise, as well as great power.
There is an area between Sinfall and Castle Nathria with the same name. The Harvesters were originally created in Sinfall, but of the original Harvesters only two remain: Prince Renathal and the Curator. The original Stonewright still exists, but she was stripped of her power; the current Stonewright was the first mortal soul to be sired to become a venthyr.
If a medallion is stolen from a Harvester, so long as it is not removed from Revendreth, the Harvesters are able to locate it by summoning manifestations of that sin from the dais of Sinfall.
Extract anima and sins through Ritual of Absolution and later either sire souls into venthyr, send them back to the Arbiter, or condemn them to the Maw; seal souls in atonement crypts until ready
Unknown Previous Harvester of Wrath — One of the original Court of Harvesters, was stripped of her power and replaced by the current Stonewright sometime before the Light's invasion of the Ember Ward. She still exists but hasn't been seen in a very long time.
Prince Renathal and the Curator predate all nathrezim.
The sins of Revendreth of each Medallion seems to be based off of the Roman Catholic Seven Deadly Sins.
The Tithelord we encounter is the 275th Harvester of Envy. The Countess has been the Harvester of Desire for so long, everyone believes she is one of the original, non-mortal venthyr like Renathal, so she may be the second Harvester of Desire. The Stonewright is the second Harvester of Desire.

The fact the Medallion of Dominion is capable of altering the fabric of the Shadowlands themselves, and its similarity to the name "Domination" used in the context of the Maw and the Jailer, hints at some connection.
Given that we defeated the Fearstalker without attempting to get her sinstone (as was done when usurping the Accuser during the leveling campaign, and as Kyrians use when attempting to coerce the Countess) and we are not explicitly told she was a former mortal (as in the case of the Tithelord), it is possible she was one of the original venthyr made from Denathrius's will.
As it is stated that Prince Renathal had control over the Ember Ward, which contained both the nathrezim in Sinfall and the venthyr of the Shrouded Asylum, it is possible he had official purview over both groups in the past.
