Description
The very name of Ashtyrannthor strikes dread into the hearts of even the bravest adventurers. Even the tarrasque seems harmless compared to this millennia-old red dragon.
In her youth, Ashtyrannthor was as hot-headed and chaotic as all red dragons. She lived for nothing but death and destruction. She destroyed towns and razed cities, delighting in the bloodshed. However, she was grievously injured by a gold dragon, and retreated to the depths of the city.
Centuries spent healing will war raged above her bored Ashtyrannthor, and she took up the study of magic. When the city was abandoned, Ashtyrannthor remained, learning her spells and waiting for the time she could conquer the multiverse and replace Tiamat as the queen of evil dragons.
Lair and Lair Actions
Ashtyrannthor lairs in the bottom level of the Lost City of Dragons. Her palace is decorated with trophies from the many enemies she has slain. With her live her two sons, Scorch and Torch. While in her palace, Ashtyrannthor has the following lair actions:
- She causes the walls and ceiling of a chamber to cave in, dealing 10d10 bludgeoning damage to anyone in that room.
- She causes lava to erupt from below the ground.
- A permanent simulacrum of Ashtyrannthor wanders the lair.
- While she is in her lair, she can telepathically speak with all her minions.
- Creatures allied to Ashtyrannthor have resistance to all damage.
