Qafiali looks and kind of talks like Varys (GoT): human, bald, red and yellow robes. Qafiali served as the Divination principal at Astralreach Academy, and was a member of the Hydra Collective.
Qafiali had inscrutable motives but was invariably linked to many happenings related to the Ends of Empyrean: he was around the Hill Giants when Lodd got a vision quest to gather the Primordial Shards and launch himself at the sky, he called to gather the Hydra Collective to decide whether to attempt to fix or shatter the barrier in response to the threat of Mother, he was suspected to have planted a Dohwar in the desk of Caen Zauber when he stole the Infinite Scroll from him, and had also taken the Book of Vile Darkness from Caen Zauber soon after. he also frequently followed and teased Bill's Bimbos, even outright thanking them for distracting Caen Zauber during that theft.
On the 15th of Airtifae, Qafiali stole the dropped Earthsplitter from Amalar Crys' body while Bill's Bimbos sealed Mother back underground. He teleported to the peak of Solithar's Spire and began to hijack the Earthsplitter, prepared for Champion form by Amalar Crys, and summoned a Prismatic Pillar (Prismatic Wall equivalent). The party sent Magnus "Johnson" Thaumalor ahead of the as they flew towards the mountain, both who arrived and tried to break through. After another round, he expanded the remaining layers of the pillar outwards, opened the Ends of Empyrean enough to bring back 2 Deities: Basilius Rex was already ready to return through Calliope and Sentence, and Beskem's massive armored boots crashed down on either side of Sedesend.
Here, he also revealed his true form - an aberration adjacent to Elder Brains, a Greater Star Spawn Emissary. He was a massive lovecraftian monster of unending tentacles and eyes who wielded Earthsplitter for that moment.
