With the aid and thanks of two compatriots from /r/teslore (Nighthawker and Queenarynen) I was able to find some interesting new things about my favorite Daedric Prince, the Taskmaster.

The memory of answers torn from fate

The destruction of all who cannot wait.

At dusk and dawn, the Rose Queen rules

While thieves of night still own the dark.

As silent spider spins webs that mark.

The broken oath and the traitor's plot,

The huntsman's horn and sharpened spear

Make wishes pacts that come to naught

When madness claims those who would appear.

Life stands death upon its head

As sweet lust joins in pools of blood.

Escape the curse with no tears to shed

As nightmares arrive all in a flood.

When mastered by the harvester of strife.

"On The Part About Skeevers, in the Morrowind Section":

At the edge of the Autumnal Forest with the Velothi Mountains at our backs, our previous night’s joviality had lessened considerably. Kishra-do joined us before departing for Mournhold, away from our hunt. Fenrig sat apart from us, bathed in a shaft of light from Secunda, keeping his dogs away from the Argonian and the Khajiit. Ingjard sat pensively, quietly murmuring prayers to Kyne. Bashnag was out collecting firewood, his nighttime foraging exhibiting all the silent cunning of a mammoth in an apothecary. Kishra-do stopped chatting to Footfalls-in-Snow, and leaned in to my ear. “Your dungmer attracts noise as well as fleshflies,” she noted with her barbed tongue, eliciting a rasping chuckle from the lizard. “Perhaps Kishra-do will offer him a chiming bell to wear so he might alert all the woodland beasts?” I was about to explain we’d face no dangers in this neck of the woods, when a hissing squeal interrupted her insults. Kishra-do leapt up, swiftly reaching for her staff, and brought it down with considerable force, piercing straight through the head of a huge rodent. Its tiny red eyes glared up at us for a moment, before Kyne gathered up the skeever’s spirit to give to Peryite.

"On The Part About Wraiths, in the Summerset Isles Section":

We followed an odd trail that Namasur had picked up in the lower forest, heading up into the high hills of ancient Auridon. The Redguard seemed puzzled, certain that the tracks were made from a fellow child of Yokuda (the footprints matched sandals his brethren sometimes wore). The way was thick with maple and larches, until a rough glade was spotted. Half-hidden among the tangle of trees and bushes, we uncovered a shrine to Peryite.

The High Elves had abandoned this overgrown monument long ago; the ivy and vines had weathered the remains of intricate carvings with their gradual rubbing, and saplings had sprouted from the stone itself. The shrine was choked by the forest's tendrils. Namasur seemed fascinated by the structure, pointing at some of the representations of the Altmer, and the story of a battle with strange, slug-like monsters he explained were probably Sload. This stonework was reminiscent of the Halls of Stories told by Nord masons along timeworn barrow walls. "Tu'whacca's mercy..." Namasur whispered to the Argonian. "See how the arch seems aligned to that mountain peak? I'd wager my sword that Masser grows brightest above this place on the summer solstice." Footfalls-in-Snow nodded with interest, and began to cut through a patch of brambles to uncover more of the fallen rubble, catching a glimpse of something odd: the edge of a circle in the ground, which seemed to pulse slightly with a faded light.

Namasur was too slow in realizing the danger. The circle span with strange runes. As the Argonian stepped over its boundary, he quickly understood his blunder: This ruined waypoint was abandoned because it was cursed. Up from the middle of the circle rose an indistinct form: an uncanny and polluted vapor. A yawn from the ether, snapping shut in a flapping mass of anger and hate. As the hooded congealed into a thicker mass, more distinct to our eyes, we made out its malevolence. A tattered shawl, roughly stitched and wafting from sharp-nailed claws, glowing a wondrous azure, which lit the glade in an unnatural and frightning glow. The fabric trailed from the phantom's cowled countenance, the tips of the cloth growing bleary. But the creature's face was sharp, a jawless skull masking the bright blue light pouring from the beast's core.

A wraith had been disturbed.

This specter of the ether was a guardian of necromantic origins, silent and thoughtless until our paths crossed. Now it stirred into our realm, ignoring Footfalls-in-Snow (who sank to his knees, weakened by the desecrated ground he had entered) but staring at Namasur with a piercing gaze. It formed a swirling sphere of frost in its hands. The bolt shot forth and narrowly missed the Redguard's head. A second magical strike was on its way, this one a gash of ice, furrowing to Namasur's feet. He leapt quickly to avoid its touch, and produced a long spear. It was the same implement he had used to bind and dismiss the soul of the ghost we had encountered previously.

"Upon my honor..." Namasur's tone was ritualistic. "Lord Frandar's spirit now consumes you!"

The Redguard's staff glowed green and red with numerous enchantmens. It formed a circular rainbow of light as Namasur span it above his head, before he somersaulted forwards, his spear following the dance as if propelled on its own. But the Redguard's hands stayed on the rod, nimble fingers increasing the velocity and ferocity of the movement. Ingjard jumped slightly as the spear left Namasur's grasp with a jolt, bowing in the air as it flew, and entered the wraith's hooded cowl as if it had been summoned to appear there. The wraith let out a silent shout, shafts of light ripping through in all directions like a sunburst as the specter's skull broke apart. The dark form jerked about, filling with light, frayed cloth burning up in a magical fire. Then a flash we all averted our gaze from. Tattered cloth gently fluttered down to the ground. The circle of runes had vanished, leaving only a small pile of ghostly remains, and the ritual dagger of a Daedric priest.

So what do you guys think? It finally looks like Peryite is getting some much needed character development, which is great in my opinion (and means I can take back my previous statement on there being nothing regarding Peryite ESO-wise, even though we have yet to see any quests or hear from the Taskmaster himself). What could these new things be implementing?
