Tzeentchians at a Khornate ritual

Created by Burning Templar

Tzaangor Priests strode purposefully around the consecrated grounds intended for the ritual, their long red robes trailing in the sands behind them. Intricately carved circles and sigils surrounded the ritual site, created to support the Khornates' Ritual of Kazgrim Bloodspawn and to ensure the summoned demon was bound to Lord Aichmos' will.
Some of the more bloodthirsty Sariant Warriors had joined the slaughter of sacrifices in the center of the consecrated lands under Kazgrim Bloodspawn's command, and would aid the ritual in their own way.
It was a Khornate ritual, thus other than that, the Templars and their Priests wielding Tzeentchian magics could merely lend indirect support - but they could turn their gaze without. It was possible that the Sigmarites would try and attack the ritual site, and they would suffer for it.
Mounted Templars and Sariant warriors stood ready to intercept any enemy attack, which would be spotted early by Tzaangor scouts on Tzeentchian disks, as the High Templar knew the worth of reconnaissance. They would know exactly when and where to strike. The defensive magics would come as a surprise to the attackers, and if some of the Stormcast or their pitiful allies would, against all odds, get to the ritual grounds - their blood would join the other, fueling demon's return to existence.
The High Templar was with his Tzaangor knights, overseeing the construction of magical defenses and coordination of their interceptors.
It was imperative that the summoning was successful, so he had come to oversee it personally. Once the demon entered their reality and was under their command, he and the cavalry would join the direct attack on the besiegers' forces.
Rows and rows of mounted, golden-armoured Templars stood at the ready, in silent, disciplined formations, awaiting his commands. Soon, they would bring Glory to the Flame, and His will would be done.
