The Idiot Demons
"T
he vibration of their song strikes discord in the life processes of all living thing" - Gerald is most definitely not a living thing, nor does he have their natural life processes. So... I don't know how effective they'll be on him.
Tarrant also proved himself quite capable of defending against Sirens, who's songs had the typical mental siren "seduce you into wandering off the bow of the ship and drown" effects.
With prep, he is also capable of creating a mental/spiritual shield that actually feeds off the power of people trying to break though, making it impossible to break through the shield via sheer power, as it simply absorbs the power of the mental/spiritual attack to reinforce itself.
Necromancy
Tarrant draws strength from death. The more dead things, the stronger he'd become. Also, he could also nullify the spell used to animate them. Also, his nature would probably devour the reanimating spell, much like it absorbs beings of dark magic.
Summon Stealing
Considering there's only two summons Gerald uses, which are Karril and the worm things...
- Karril can't be bound or controlled, and he's not so much being summoned as he is politely responding to Gerald's request to come over. I'll make a profile for him momentarily, but I don't think he'll be that big a thing in the fight... probably.
- The worm things. Here's some quotes.
He watched as the tendrils of violet dissolved, becoming a thick purple fog that surrounded Senzei, clinging to his skin. There seemed to be movement within its substant; Damien Worked his senses to let him take a closer took - and stiffened in horror as he Saw. For the cloud was not a cloud at all, but a swarm of creatures too tiny for the unWorked eye to see. Wormlike, hungry, then searched for the surface of Senzei's skin until they found a pore or other opening large enough to admit them. Then, they slithered in, their microscopic tails lashing from side to side as they worked their way deeper and deeper into his flesh.
That quote is from when Gerald is using the worms to "heal" Senzei, by having the worms eat the diseased and rotting flesh. When he actually uses them in combat...
In answer to the rakh, Tarrant simply stared.... the pale grey eyes seemed to take on a light of their own. An unnatural light, that seared one's vision but offered no real illumination: coldfire. For a moment even the rakh were fascinated, and though no weapon was lowered it was clear that, for the moment, no one would strike. Like animals led to the slaughter
Damien though grimly, mesmerized by the flash of sunlight on the butcher's knife blade
. Then suddenly, the lead rakh cried out. His body convulsed in wavelike spass, which rippled through his flesh with almost audible force. A cry escaped his lips - pain and terror and fury all combined, a wordless screech of agony that man Damien's flesh crawl - a sound so like the death cry of Tarrant's last kill that for a moment it was as though they were down in the canyon, listening to that cry again. And then, as quickly as it had begun, it was over. The rakh's body fell to the ground, spasmed once, and then was still. Thick blood, blue-black, stained the fur about its mouth, oozed from the eyes and ears. And its groin. Damien felt his own testicles draw up in cold dread as he forced himself to look away, tried no to consider what manner of internal damage might give birth to such seepage.
"Any other objections?" Tarrant asked quietly
...
Damien forced his thoughts back onto their circumstances and forced his gaze to follow theirs, to the fallen rakh's body. Already it had begun to decompose, as if the flesh itself was anxious to decay. As they watched, deep purple carrior larvae crawled in the body's shadowed contours.
So Rasalom better be able to A) tell that there's microscopic worms inside him and B) take control of them before they eat him alive from the inside out.
Rasalon's concentrated evil
Nothing really new to Gerald. He lives in concentrated evil. Here's the description of the Forest in which he lives.
The Forest, called Forbidde
in all the ancient texts. What did they know of it, even here? It was a focal point of the wildest fae, which in an earlier, less sophisticated age had been called evil
. Now they knew better. Now they understood that the forces which swept across this planet's surface were neither good nor evil in and of themselves, but simply responsive
. To hopes and fears, wards and spells and all the patterns of a Working, dreams and nightmares and repressed desires. When tamed it was useful. When responding to man's darker urges, to the hungers and compulsions which he repressed in the light of day, it could be deadly. Witness the Landing, and the gruesome deaths of the first few colonists. Witness the monsters that Damian had fought in the dividers, shards of man's darkest imaginings given fresh life and solid bodies, laying traps for the unwary in the icy wilderness.
Witness the Forest.
"Sheer concentration makes the fae there too strong to tame," she told him. "Manifestatial response is almost instantaneous. In plainer English, merely worrying about something is enough to cause it to happen. Every man that's dared to walk in those shadows, regardless of his intentions, has left some dark imprint behind him. Every death that's taken place beneath those trees has bound the fae to more and greater violence. The Church once tried to master it by massive applications of faith - that was the Great Wars, as I'm sure you know - but all it did was give them back their nightmares, with a dark religious gloss. Such power prefers the guarded secrets of the unconscious to the preferences of our conscious will"
And
"Look at your map again. The Forest sits at the heart of a whirlpool, a focal point of dark fae that draws like to like, sucking all malevolent manifestations towards its cente
And
"There's a creature that lives within the Forest - maybe a demon, maybe a man - which has forced a dark sort of order upon the wild fae there. Legend has it that he sits at the heart of the whirlpool like a spider in its web, waiting for victims to become trapped in its power. His minions can leave the Forest, and do, in a constant search for victims to feed him."
"You're talking about the Hunter"
Numbers advantage
I'm assuming Tarrant is not bringing any of his Forest creatures, because even with prep time that's not really in-character, the only thing he ever brought with him were horses. But even so...
Tarrant also states that he'd be reasonably confident he could singlehandedly take on an army of demons with all his power, so I don't think the numbers advantage would be that great. He's also capable of killing multiple people at once, and could likely freeze an army of rats solid simply from the AoE of his coldfire and coldfire sword.
