Kharvex, the Shadow Caller

• Cult mage of the Cult of the Eclipse, trusted directly by the Weaver
• Tasked with conducting experiments at the ancient battlefield where Nidhogg was sealed to harness residual energy from the original sealing ritual
• His goal was to channel that dormant power into the summoning spells contained in his spellbook, amplifying their connection to the Shadowfell
• Creator of the Grimoire of the Eclipse
• Defeated by the party at the ancient battlefield; the Grimoire was recovered by the party

Grimoire of the Eclipse

Description

Manus

• Enigmatic CR 17 shapechanger and trickster warrior loosely allied with the Cult of the Eclipse
• Serves the Weaver as a lieutenant but openly mocks his ideology and appears motivated by testing himself against worthy opponents rather than freeing Nidhogg
• Possesses Advanced Shapechanger abilities — can perfectly mimic other humanoids, as demonstrated when he disguised himself as Trius at the Summer Court leyline temple
• Master of shadow and elemental combat — conjures elemental blades of cold, fire, lightning, or poison and creates up to four shadow copies of himself
• Stole the Summer Court’s leyline crystal and planted the Bodak in the Spring Temple
• During the final battle at the ancient battlefield, the Weaver’s desperate shockwave pushed him too far — he turned on the Weaver in fury: “This is too far — I didn’t sign up for this!”
• Current whereabouts unknown following the Weaver’s death; allegiances remain unresolved

Personality & Motivation

• Driven entirely by a desire for meaningful combat — not money, power, or ideology
• Finds the Weaver’s mission tedious but participates because it generates interesting conflicts
• Made a verbal agreement that the Weaver would duel him after Nidhogg’s release — but grew skeptical the Weaver would honor it; the Weaver’s death rendered the agreement moot
• Increasingly views the party as more worthy opponents than anyone in the Cult of the Eclipse
• Theatrical and playful in combat — taunts opponents, proposes games, and retreats when bored rather than fighting to the death

The Summer Temple Encounter

• Appeared outside the Summer Court leyline temple disguised as Trius (the Winter Court paladin)
• When confronted, dropped the disguise with a grin and proposed a game: if the party could land one blow on him, he’d return the stolen rune crystal
• Proved nearly impossible to hit — dodged effortlessly and teleported around the party
• Slumpet won the game by throwing a handful of ball bearings at his feet, technically “landing a blow”
• True to his word, Manus handed over the crystal and vanished with mocking praise for their ingenuity
• The returned crystal was later discovered to be tainted and could not be restored without knowledge from the Chained Library
• “Drawing broken swords now, bird? I do hope you brought sharper company.”

The Mountain Peak Confrontation

• Intercepted the party at Evenode Peak (Tael’anore) in the Feywild, where Elara Sunforge’s device was set to capture the “First Kiss of the Midday Sun” for reforging Summer’s Edge
• Snapped his fingers and created magical darkness covering the entire peak, denying the party the sunlight they needed
• Created two shadow copies and fought the party in the dark, where only Skreek (with blindsight) could perceive him
• Shad dispelled the darkness, and Manus showed genuine respect before retreating into the shadows
• “Oops. Looks like your precious kiss of the sun just got lost in the dark. Good luck finding it now.”
• “Well, well, well. Color me impressed. Didn’t think you had that in you. Guess I’ll have to step up my game next time.”

The Bodak Note

• Planted a Bodak in the Spring Leyline Temple’s crystal chamber using Oil of Etherealness, causing major corruption to the temple and surrounding forest
• Left a letter in the Bodak’s robes addressed to the party — effectively betraying the Weaver’s plans:
  • Revealed the Weaver accelerated the final ritual from the winter solstice to the next new moon (~12 days away)
  • Disclosed the ritual location: the ancient battlefield where Nidhogg was sealed
  • Expressed growing interest in fighting the party over honoring his deal with the Weaver
  • Invited them to “crash the party” at the ritual
• “The Weaver is practically pulling his hair out over your little stunt with that Hollow Threshold. Watching him scramble has been the most entertainment I’ve had in decades.”
• “I do hope you’ll crash their little party. The Weaver plans to execute his grand ritual at the ancient battlefield where Nidhogg was sealed away ages ago.”
• “I’m starting to think you might give me a better fight. You certainly fight with more style than his shadow-drunk cultists.”

Cult Operations

• Stole one of eight rune crystals from the Summer Court leyline temple, destroying two guardian constructs in the process (using fire and ice magic)
• Planted a Bodak accompanied by wraiths and shadows in the Spring Temple’s crystal chamber
• Both operations occurred while the party was in the Feywild, where time flowed differently — allowing weeks to pass on the Material Plane
• His actions technically serve the Cult of the Eclipse’s goals of weakening the leyline barrier, but his letter to the party suggests he may be deliberately undermining the Weaver for entertainment

Relationship with the Weaver

• Operated as the Weaver’s most powerful agent but showed no genuine loyalty
• Openly mocked the Weaver and dismissed his ideology as tedious
• Viewed the Weaver primarily as someone who promised him a duel — a promise he doubted would be kept
• The Weaver listed Manus’s disloyalty as a known vulnerability in his own plans
• By revealing the ritual’s location and timeline via the Bodak note, Manus effectively acted as an unwitting (or deliberate) double agent
• At the final battle, turned on the Weaver in open fury when the shockwave crossed a line — the relationship ended with the Weaver’s death

The Ancient Battlefield — Final Battle

• Welcomed the party at the ritual site with arrows, plainly delighted they had come
• Was locked in a daze by Shad’s Confusion spell for a crucial round
• The Weaver screamed at him as the ritual faltered: “What am I paying you for! This is what we’ve been working towards for so long. It’s time to get serious and earn your keep!”
• Reluctantly summoned two shadow clones: “Fine, but I’m not sure this ritual is really going to be worth it”
• When the Weaver’s desperate shockwave of pure force detonated across the battlefield, Manus wheeled on him in fury: “This is too far — I didn’t sign up for this!” — and appeared ready to switch sides
• The Weaver was killed by Trius’s Moonbeam before Manus could act further
• Did not fully commit to attacking the party during the battle — his ultimate allegiance in that moment remains unresolved
• Current whereabouts unknown

Relationship with the Party

• Shows a pattern of escalating respect across encounters
• First encounter: tested them with a game; rewarded their cleverness
• Second encounter: tried to deny their mission; acknowledged their strength when they overcame it
• Third contact (the note): actively encouraged them to disrupt the Weaver’s plans
• Final battle: fought alongside the Weaver reluctantly, then turned on him — but never attacked the party
• Addresses Shad directly with taunts about his “broken sword” and feathered appearance
• Views the party as increasingly “interesting” — the highest compliment in his personal philosophy

Post-Weaver Status

• The Weaver’s death severs Manus’s formal cult affiliation
• His promised duel with the Weaver never happened — leaving that particular score unsettled
• May resurface seeking the party for the fight he’s been building toward
• With the immediate threat of Nidhogg averted, his next move is entirely his own
