Vish Kal, Blood Arbiter

As far as their servants and allies are left to believe, the dragonlords and their broods dominate every inch of Tarkir, and nowhere is free from their clawed grip. But high in the Qal Sisma mountains, a single vampire by the name of Vish Kal claims a stronghold independent of even the dragonlords. Even the Artaka brood and the Temur-Frontier do not hunt here, for fear of the Blood Arbiter's judgement and sentencing. Watcher from the Peaks Vish Kal is an ancient vampire, almost as old as the dragonlords, but is not of the native race of Kheru vampires. Vish Kal's progenitor was a strange visitor from an infinitely distant land, one who Vish Kal has not seen since. Vish Kal has lived almost all of his un-life in the highest peaks of the Qal Sisma range, separate from the rest of Tarkir, an aloof and forbidding judge in a world ruled mostly by instinct. Code of the Arbiter In ancient times, and in a Takir where Ugin fell to Nicol Bolas, Vish Kal was and is an ancient presence in the lives of Tarkir's people. A presence rarely seen but always felt, the races of Tarkir treat Vish Kal with a universal respect, seeing the vampire as an impartial judge and moral guide. Vish Kal himself feeds only from those who openly flaunt his strict code of ethics; the same ancestral code Tarkir's culture developed centuries ago, and which Vish Kal has held since his life as a human. For those with roots in the past, Vish Kal's presnece holds the line, and his decisions are always fair. For those with an eye towards the future, he is a remnant of times past, and a blight which restricts the growth of Tarkir as a whole. Vengeful Revenant In a world where Ugin survived his wounds with the help of Sarkhan Vol, and here dragons hunt freely, Vish Kal's position is tenuous, and his independence strongly defended. Vis Kal no longer freely hunts the night as he once did, passing judgement on those who break with tradition. Now, the dragon broods have destroyed Tarkir's heritage and culture, and Vish Kal holds them responsible for what he sees as the death of the true Tarkir. Vish Kal sits on a throne carved from the rock of one of Qal Sisma's highest mountains, in armor crafted from the bones of a now-extinct brood which he personally hunted don and exterminated. His people, both the cultures of Tarkir to which once belonged and the other vampires of his kind, are as dead as the dragons hose skull's he displays as trophies. No he sits and waits, feeding eah night indiscriminately, having long ago judged all that remains of Tarkir as guilty beyond redemption. Vish Kal, Blood Arbiter's Lair In a Tarkir without dragons, Vish Kal has no lair, instead hunting the skies over all of Tarkir and only returning to his mountain home at the first sign of dawn. In a Tarkir where the dragonlords reign, Vish Kal's lair is high in the Qal Sisma mountains, on a plateau which centuries ago was the roost of a now-extinct breed of dragons. When encountered in his lair, Vish Kal, Blood Arbiter has a Challenge Rating of 19 (22,000 XP.) Lair Actions On imitative count 20 (losing initiative ties), Vish Kal, Blood Arbiter takes a lair action to cause one of the following effects; Vish Kal can't use the same effect two rounds in a row

Vish Kal vanishes in a puff of black smoke, immediately reappearing in any unoccupied space of his choice within his lair.
The bones of dragons which Vish Kal keeps as trophies suddenly animate, flying from the walls, razor sharp claws and teeth bared, filling a 20-foot cube centered on a point of Vish Kal's choice. Each creature which starts its turn in the cube or enters it for the first time on its turn must make a DC 18 Dexterity saving throw, taking 3d6 slashing damage on a failed save, or half as much on a success. This effect ends after one minute, or if Vish Kal dies, is knocked unconscious, uses a bonus action to end the effect, or uses this lair action again.
Vish Kal creates two duplicates of himself, each of which acts at the end of his turn. The duplicates have the same statistics as Vish Kal, except that each has a number of hit points equal to half of Vish Kal's remaining hit points (rounded down). The duplicates remain until reduced to 0 hit points, until Vish Kal uses another lair action, or until Vish Kal dismisses them as an action. If a duplicate is reduced to 0 hit points it disappears, and Vish Kal takes 10d8 psychic damage.

Regional Effects The region containing Vish Kal's lair is warped by the vampire's magic, which creates one or more of the following effects

The sky within 10 miles of Vish Kal's lair is covered with clouds, preventing any sunlight from coming through, as if it were perpetually nighttime.
Vish Kal automatically detects the presence and number of any living creatures within a day's travel of his lair, but not their location.
Vish Kal can automatically cast the scrying spell three times per long rest while in his lair. Vish Kal is considered to have firsthand knowledge of any creature on Tarkir for the purposes of determining the bonus granted to saving throws against this spell. Creatures which have previously failed this saving throw or whom Vish Kal has personally met have disadvantage on this saving throw.
