Once Crowley and Nytheadon unseals the energy inside of flame and storm orb, they would be complettly surrounded with its energy. Their Voiceless marks brighting glowly as it leads the ritual and spell of Storm and Flame. The energies wrapping over them like a blanket or layer of skin. Crowley eyes complettly devoured by the energy of Aes as Nythaedon's strikes with flames. They would start both at same time do same verbal gesture as the energy upon them start growing and getting stronger aura. The flame of Nytheadon would begin to crack and make loud noises, Crowley's control over lightning would slowly manifest around his hands into lightning cracking runes. As they would start to pronounce an ancient incantation, they energy slowly start to be removed from the, unleashing into thin particles, almost as it seems that the incantation is failing.. but even with energy gone.. the wind start gathering on strenght.. it starts to move grass beneath their feets, moving with tree tops, as the flame would suddenly outburst in huge vortex surrounding everyone in few yards, however.. the flame seems to work like a prison to not let enemies escape from it.. as Nythaedon starts making like whirl movement with hand.. the flame vortex would start to whirl aswell, Nyth seems to have great focused over it, and each movement with hand costs him a lot of effort.. as if whirling something very heavy. The Whirling vortex, would slowly start unleashing flame waves, flurry of flames from its edge of vortex walls, striking upon enemies and damaging them. The heat would not seem that high.. however the heat of flame flurries and waves which are striking upon enemies seems to be enough to melt trough flesh, even bones. The flame vortex, seems to be crackling and making loud noises, as nothing can be seen from within only.. it its whirling flaming and spinning walls. Nythaedon's hand would be focusing a great orb of flame to keep focus and power of such spell and primal essence. However, it would have some toll upon him, and his hand is steaming from, maybe even burned hand upto wrist...Once he focuses this spell.. Crowley riases his own hand as the power of storm manifests crackling orb, similiar to what Nythaeadon had.. he would slowly leap few inches from ground almost as if something is lifting him, as he begins to pronounce own incantation towards the skies, they would get darker.. and more louder.. almost as if preparing to end of world.. the energies emitating from orb.. holding enough power.. to shape magic in skies into powerfull storm.. he would remain in pronounce the incantation as the energy from orb seems to be extending. The rain would start falling down.. upon sorched enemies, fighting Revenants.. washing the.. caused blood from ground and their armor. Crowley would then shout the last part of incantation as the orb implodes, and skies whirls forcefully.. releasing volley of lightning bolts from above upon the enemies down. The storm.. hovering over the eye of fire vortex.. would seem to be made of primal forces.. something old and powerfull.. The lightning strikes with thunder, and the sorching noise of vortex around them, would seems almost scary.. but none of it.. would hurt Revenants. As soon as Crowley and Nythaeadon unleshes their powerfull spells from artifacts they held.. they would drop on knees, heavily panting and even unable to see probably for while.. After all.. every spell has its toll, and this was one big spell.
