Therana
Contrary to her prior thoughts, it seemed that Therana possessed the advantage of surprise in this scenario. She savored this feeling of control, the empowering thrill of a predator stalking its prey coursing throughout her being. It was always in these scenarios that Therana felt most alive. Her senses sharpened in instinctive response, her mind accelerated its thought processes and drained away excess thoughts to leave behind but a peerless dedication to a single goal, and her mindset underwent a paradigm shift towards one exceptionally conducive towards success in this scenario. Therana took in a deep draught of breath, inhaling in the rather stuffy and overly air conditioned air of the store that was laced with the homely smell characteristic of produce isles. A slight throbbing pain pulsated from both her shoulders where the two alien flesh masses wriggled, probing the air for a foreign presence with their current bodies morphed to possess a layer of skin riddled with hyper sensitive organisms that scoured the surrounding air for the slightest of environmental differences. These two monsters fed off of Therana's own body of course, but their usefulness and longevity far overshadowed the drain cost of maintaining them. In any case, Therana could feed them the magical energy stored in her magic crest in the case that her own body sustained too much strain.
If these organisms had been found by the Association, they would have been branded as rare treasures almost miraculous in their potency and mystery, rivaling the pricelessness of phantasmal beast specimens of renown. With the remarkable ability to morph their alien bodies at Therana's whim and alter intrinsic biological aspects of their being, the serpentine parasites served as sword, shield, and bow concurrently. The fact that their extra-dimensional constitution allowed them to produce substances native to the dimension of Horrors and almost completely unknown in this current realm also aided their lethal potency, as any toxins produced by them would nearly always be invariably fatal simply on basis of having never been encountered before and having a constitution unable to be neutralized by simple healing magic mysteries. They were monsters described of only in texts that detailed horrors representing the absolute evils of humanity - beings geared towards the most efficient slaughter of mankind possible. A certain french noble in the Hundred Years War had attained a means of accessing these beings through the usage of a marvelous mystic code, but Therana was unique in that her very being was connected to this dimension. This connection allowed her to completely subvert the complex rituals required to manifest beings from other dimensions, letting her body become a conduit or pathway from which monstrosities from this alien dimension could arrive. Of course, Therana would not be able to control these beings once they entered the current realm as she merely invited them, which is why she highly preferred to operate with select beings that she had implicit trust in or could be fully controlled through a symbiotic relationship such as with her current two parasites.
With elegant, graceful steps, Therana navigated through the aisles with inhuman speeds, her body currently being reinforced by a spell unique to the magical system of the horrors. A pattern of coal black energy streaked throughout Therana's limbs to signal this reinforcement, taking a chaotic breaking pattern that caused Therana's limbs to appear as if they were porcelain extremities shattering. She spotted the Executioner soon enough, and immediately she found dislike for him. He appeared to be an utter idiot to her, blithely ignoring his environment. Such people wasted the Earth's blessings in Therana's opinion, and she sought to end the burden upon the planet soon enough. Standing utterly still behind an aisle of groceries nestled in the Executioner's path, Therana waited until he came within seven meters of her being. As soon as the Ashen Mandrake stepped within Therana's maximum active range of ten meters, she had reinforced her two serpentine parasites. When he had tread within eight meters of her, Therana casted an otherwordly spell,
"Fm'latgh"
Immediately one of the parasitic protrusions changed its shape into a bulbous wart shaped mass of flesh that tapered off into a circular mouth inlaid with hundreds of encircling teeth. Noxious slime with the same consistency of pus spewed forth from the parasite's skin, dripping onto the ground in thick, viscous rivulets so caustic as to burn through the ground two inches. When the Executioner was within seven meters of range, the engorged parasite released its contents, ejecting a highly pressurized blast of plum purple fluid aimed at the man's torso in an attempt to completely incapacitate him and to reduce margin of error for the attack's strike area.
