Ajani - Turns off magic

Ajani’s vision clouded. Around him he saw only the streaks of mana—nature magic, magic of fire and rage, magic of healing and protection, and others—thrashing back and forth between the humanoids and Sarkhan’s flight of rage-blooded dragons. All of them were fueled by bonds of mana, bonds that anchored their magic to the power inherent in the realms of Alara. To his surprise, Ajani could perceive the bonds directly, as if they had been beams of light revealed by smoke. He saw traceries of connection and correspondence all around him, joining every mage and monster with their sources of power all over the world. The volume of mana flowing from all corners of Alara was enormous, all cascading to the maelstrom at the intersection of all the shards.

It had to stop. He had to staunch the flow somehow.

Ajani saw his own mana bonds, bonds not only with Naya, but with the volcanic shard of Jund where he had first planeswalked. He saw the cauldron of lava into which Sarkhan had vaulted, and into which he threw himself in a moment of glory and rage. He summoned mana from all sources he knew, and cast it all out in one savage roar.

Energy blasted outward from Ajani, throwing a metaphysical gust around the maelstrom gorge. The blast shook the earth with one savage jolt, and for a moment, everything stopped. Mages and dragons both halted their assault, and looked around bewildered.

The outburst of rage subsided, and became a simple breeze ruffling Ajani’s fur.

All the combatants recovered then, and attempted to rejoin their fight—but found that their mana bonds had all been severed. They had no mana to fuel their spells, and the essence of the dragons’ flames had drained away.

***

Ajani had only a dim sense of the action around him, of the elves and nacatl attempting to attack Bolas. As Ajani had destroyed their mana bonds, the humanoids were powerless to attack him.
