Traits

Aura of Solar Dominion. Allies of Caelthir’s choice within 30 feet of him have advantage on saving throws, resistance to necrotic damage, and deal an extra 6 radiant damage on melee weapon attacks. Undead and fiends in the aura have disadvantage on saving throws against being frightened and against radiant effects.

Tyrant Spirit Manifestation. Once per turn when Caelthir hits with a melee weapon attack, the target takes an extra 21 (6d6) radiant damage.

Legendary Resistance (3/Day). When Caelthir fails a saving throw, he can choose to succeed instead.

Actions

Multiattack. Caelthir makes three attacks with his Solar Tyrant Blade.

Solar Tyrant Blade. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 6) slashing damage plus 13 (3d8) radiant damage.

Smite of the Crimson Sun (Recharge 5–6). Caelthir emits a wave of blazing Positive Plane energy in a 30-foot cone. Each creature in the area must make a DC 20 Constitution saving throw, taking 54 (12d8) radiant damage on a failed save, or half as much on a successful one. On a failed save, a creature is also blinded until the end of its next turn. Undead and creatures native to the Negative Plane take an additional 18 (4d8) radiant damage.

Radiant Tyrant’s Roar (1/Day). Each enemy of Caelthir’s choice within 60 feet that can hear him must succeed on a DC 20 Wisdom saving throw or be frightened for 1 minute. While frightened in this way, a creature takes 10 radiant damage at the start of each of its turns. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Bonus Actions

Burning Command. One ally within 30 feet of Caelthir can immediately use its reaction to make one weapon attack with advantage.

Fey Step (Recharge 4–6). As a bonus action, Caelthir magically teleports up to 60 feet to an unoccupied space he can see. Each creature of his choice within 10 feet of the space he leaves or arrives in takes 14 (4d6) radiant damage.

 

Reactions

Radiant Rebuke. When a creature within 10 feet of Caelthir hits him with a melee attack, that creature takes 14 (4d6) radiant damage.

Legendary Actions

Caelthir can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Caelthir regains spent legendary actions at the start of his turn.

Solar Step. Caelthir teleports up to 30 feet to an unoccupied space he can see.

Tyrant Strike. Caelthir makes one Solar Tyrant Blade attack.

Blazing Pulse (Costs 2 Actions). Each enemy within 15 feet of Caelthir takes 14 (4d6) radiant damage.

Description

Caelthir Pyrosun stands clad in blazing crimson fey-plate shaped like the skull and scales of a titanic primordial lizard. His helm bears the crowned visage of a roaring drake-tyrant, its maw glowing with golden fire. Ember-veined plates form overlapping “scale” segments across his armor, and a radiant crest flares behind him like a burning mane.

When he moves, spectral fey-fire footprints briefly resemble massive reptilian claws. In battle, a towering, translucent tyrant-lizard spirit looms behind him, mirroring his strikes like a divine avatar.

His presence is overwhelming — warm as a summer sun, commanding as a warlord, and terrifying to creatures of darkness.


Lore

Caelthir Pyrosun is the Crimson Warden of the Summer Court, a chosen champion of the Positive Plane who embodies vitality, courage, and the unstoppable force of life itself. In ancient fey legend, he was chosen when a living fragment of primordial life-energy — the Solar Tyrant Spirit — bonded with his soul.

Unlike many eladrin knights, Caelthir does not rely solely on grace and trickery. He is the hammer of the Light Rangers — the one who meets apocalyptic threats head-on.

He is revered among the Light Rangers as their spearpoint in planar wars against undead legions, void entities, and Negative Plane incursions. When Caelthir is summoned, it is because something must be broken, burned away, and ended forever.


Where Players Might Encounter Him

Players may find Caelthir in:

  • The Bastion of Everdawn, a radiant fortress floating on the edge of the Positive Plane

  • The blazing heart of a Feywild Summer Citadel

  • Battling an undead god or Negative Plane incursion

  • As a summoned champion during a planar convergence

  • Guarding a life-font nexus where Positive Plane energy pours into the multiverse

He may serve as:

  • A powerful ally

  • A quest-giver

  • A test of worth

  • Or a last-resort reinforcement in a world-ending battle

    Personality

    He respects warriors who stand their ground — even former enemies.
