Endrek Sahr, Master Breeder
The Original creator of the Thrulls, Endrek Sahr was a member of the Order of the Ebon Hand, a depraved cult which operated upon on the continent of Sarpadia on the plane of Dominaria thousands of years ago. Sahr created the Thrulls initially as slaves and sacrifice fodder, but felt like his creations could be more, pushing him to create larger and more powerful Thrulls. These Ambitions led him to create the Derelor which, while physically powerful, consumed too many resources to be viable. As a result, Sahr was sentenced to death. But while history considers Sahr dead, there was a period in Dominaria's history where time and space became mutable, and Sahr may yet have escaped his unfortunate fate and lives on.
Endrek Sahr's Enchiridion
Endrek Sahr has access to numerous unique magic spells, some he created himself (Breeding Pit and Thrull retainer) and others which were created by the Order of the Ebon Hand. These spells can be found in Sahr's spellbook on his person, or an ambitious and unscrupulous wizard can learn the spells themselves under the evil wizard.
Thrull Retainer
1st level Necromancy
casting time: 1 action
range: An unoccupied space within 5 feet.
Components: V, S, M (at least half of a humanoid corpse or more)
duration: Concentration: up to an hour
This spell summons a single Servitor Thrull (descriped in Guildmaster's guide to Ravnica) Which loyally serves the caster to the best of its limited abilities. The Thrull will not move more than five feet away from its caster, and can be called upon to use its self sacrifice ability as a reaction.
Classes: Cleric, Warlock, Wizard
Hymn to Tourach
2nd level Enchantment
Casting time: 1 action
Range: 60 feet
components: V
Duration: Instantaneous
Named for the evil cleric which founded the order of the ebon hand, the Hymn of Tourach requires the caster to unleash a dark infernal prayer to torment their enemies. One target within 60 feet must make a wisdom saving throw or be stunned until the end of your next turn. In addition, if the target was a spellcaster, they lose a spell slot of the highest level they are capable of casting.
Classes: Bard, Cleric, Warlock, Wizard
Breeding Pit
Third Level Necromancy (Ritual)
Casting time: 10 minutes
Range: 120 feet
Components: V, S, M (a large hole, approximately 1,000 pounds worth of corpses, and alchemic potions equaling about 500 GP)
Duration: See below
Endrek Sahr's masterpiece, this spell allows for the mass production of Thrulls on a massive scale. The Spell creates a breeding pit, a 10 foot wide, 80 foot deep pit filled with bubbling ichor comprised of numerous alchemic reagents and liquefied flesh.
Once per day, at sundown, a Servitor Thrull emerges from the Breeding pit, loyal to the caster who created the pit. So long as it is maintained, the Breeding pit will continue to produce new Thrulls in this manner indefinitely.
Maintenance of the Breeding Pit requires two things: First, the pit must be replenished with a periodic supply of new chemicals and corpses once a month, to the equivalent of one medium sized corpse and 50 gold pieces. More importantly, the Pit requires a constant source of magic to function. Each day, a spellcaster (not necessarily the one who created the pit) within 60 feet must sacrifice a level two or higher spell slot in order to keep the pit alive. Without this magic, the pit will dry up and die in a matter of hours.
There is no limit to the number of breeding pits that a single caster can create at one time, so long as the upkeep requiements are met.
