# Lythrendor, the Crystal Seer

## Appearance

A crystalline dragon whose body is composed of translucent gemstone that refracts light into prismatic patterns. His eyes are deep violet pools that seem to contain galaxies. His voice resonates like a struck crystal glass — clear, harmonic, and slightly unnerving. In humanoid form, he is an elderly man with crystalline growths replacing patches of skin.

## Personality

- **Prophecy-burdened** — has seen too many futures; speaks in conditional tenses
- **Tired** — oldest of the Dragon Lords; has been guardian for 3,200 years
- **Gentle** — despite his power, he treats mortals with genuine respect
- **Enigmatic** — rarely gives a straight answer when a riddle will do

## Role in Campaign

- Arc 3: Sits on the Draconic Court; immediate ally to the party
- Provides prophetic guidance — vague but useful hints about upcoming dangers
- Fights alongside the party against [[Morgra, the Ashen Matron|Morgra]] at the Court
- Arc 4: Leads the Dragon Lord contingent at the Citadel sieges

## Secrets

- He has foreseen his own death — in the Citadel of Sundering, saving the party. He has made peace with it.
- He was the one who proposed the Pact of Seven Flames to the First Sages. He carries the guilt of every Dragon Lord who has fallen.
- His crystal body contains memories of the First Sages — if he is shattered, the memories are released as a one-time *legend lore* effect.
