Meridia, the Radiant Arbiter

Alignment: Lawful Good (with a hint of Neutral tendencies)
Domain Influence: Light, Life, and Purity
Symbol: A radiant sunburst encircled by a ring of prismatic light
Plane: The Auroran Spire, a resplendent demiplane of eternal dawn

Core Concept

Meridia is a cosmic entity devoted to the eradication of undeath and corruption. In the Elder Scrolls, she despises necromancy and the undead, and that theme translates perfectly into D&D. She becomes a Celestial Power or Outer Plane Patron, revered by paladins, clerics, and even warlocks who seek to cleanse the world of darkness.

Personality & Ideals

• Purity Above All: Meridia views undeath as a perversion of the natural cycle. Her followers are tasked with restoring balance and burning away corruption.

• Radiant Justice: She is not merciful to those who willingly embrace necromancy or shadow magic. Her justice is swift and absolute.

• Order Through Light: While benevolent, Meridia is authoritarian in her approach—her light is not negotiable.

Appearance

Meridia manifests as a towering figure of living light, humanoid in shape but with prismatic wings and a halo of eternal dawn. Her voice resonates like a chorus of bells, and her presence banishes all shadows.

Auroran Spire (Her Realm)

• A vast crystalline citadel floating in a sea of golden light.

• Rivers of radiant energy flow through gardens of glass flora.

• Souls who served her faithfully dwell here as Aurorans, luminous beings who act as her emissaries.

Followers

• Clerics: Often of the Light Domain or Life Domain.

• Paladins: Oath of Devotion or a custom Oath of Radiance (focused on destroying undead and purging corruption).

• Warlocks: Pact of the Celestial, with Meridia as their patron.

Tenets of Meridia

1. Destroy the Undead: They are an affront to the cycle of life.

2. Protect the Living: Life is sacred and must be preserved.

3. Spread the Light: Darkness breeds corruption; illuminate all shadows.

4. No Compromise with Evil: Mercy for the wicked is weakness.

Artifacts

• Dawnbreaker (Legendary Weapon): A radiant longsword that explodes with holy fire when striking undead.

• Prism of Purity: A crystal that can banish necrotic energy and cleanse cursed lands.

Adventure Hooks

• A cult of necromancers has stolen a shard of Meridia’s essence, corrupting it into a weapon of darkness.

• A forgotten temple of Meridia lies buried beneath a city plagued by undead—her light must be rekindled.

• A rival celestial accuses Meridia of tyranny, sparking a divine conflict that mortals are dragged into.

Would you like me to expand this into a full playable supplement for D&D 5e (including stat blocks for Meridia, cleric domain, paladin oath, and magic items) or write a short campaign arc centered around her influence?

Design a paladin oath for Meridia AND Write a cleric domain for Meridia

Here’s a full design for both a Paladin Oath and a Cleric Domain dedicated to Meridia:

Paladin Oath: Oath of Radiance

“The light of Meridia burns away corruption and undeath. You are her blade and her beacon.”

Tenets of Radiance

1. Cleanse the Taint: Undeath and necromancy are abominations. Destroy them wherever they arise.

2. Illuminate the Shadows: Bring truth and light to places of darkness and despair.

3. Protect the Cycle: Life and death are sacred; do not allow their natural order to be broken.

4. No Mercy for the Wicked: Those who embrace corruption must be purged without hesitation.

Oath Spells

Channel Divinity

• Radiant Purge: As an action, present your holy symbol and speak Meridia’s name. All undead within 30 ft. must make a Constitution save or take radiant damage equal to your paladin level + Charisma modifier.

• Light of Judgment: You can imbue your weapon with radiant energy for 1 minute. It deals an extra 1d8 radiant damage on hit, and undead struck by it must succeed on a Wisdom save or be frightened until the end of your next turn.
