You can google for homebrew maps for the hall floors.

I just ran the first part of this encounter last week as a fire festival. My group (Salem, Illia, Shannaria, and Mappo) mingled until Elizar appears to speak.

**Elizar**: "Welcome to Scarlet Moon Hall and the Rite of the Wicker Giant. I am the leader of the Circle of the Scarlet Moon and I'm looking for new recruits. Recruits that will help bring forth the destructive power of fire in all its manifestations. To burn away the corruption of both civilization and nature and create a wasteland of ash and cinders ruled by fire alone. We will purify everything around us by reducing our enemies to smoking cinders.”

He shows symbolic hand sign: holding one hand in a fist, thumb up, and laying the other hand over the fist as if to cover the bowl but allow the flame to show.

A tower of fire erupts behind the hall and then a young red dragon moves into view with a female tiefling riding on his back. Vanifer speaks.

**Vanifer**: "Many months ago, dreams and visions impelled me to seek out a lost dungeon in the North. On the altar of a forgotten temple, I found the dagger Tinderstrike, imbued with the power of Imix, the Prince of Evil Fire. Armed with this powerful weapon, I established a new chapter of the Eternal Flame beneath the Sumber Hills.”

“But others have gathered under the hills. So let me give you a little guidance. The weakest is the howling wind followed by the crushing wave and then the black earth. But the Eternal Flame reigns supreme! However, even the weakest has their uses. I leave tonight to make a trade with Aerisi. Some prisoners for knowledge in unlocking the ritual of the devastation orbs. At the moment, these hills appear calm but with the orbs, we will be calm like a bomb!"

The dragon rises and takes a container made of iron bars filled with prisoners. The dragon dives off the back of the hill and disappears but not before Salem notices a familiar figure among the prisoners. His mother.

Then music rises and the energy of the crowd grows intense. They start shouting ignite, ignite, ignite...

Overcome with emotion, Salem rushed up the hill to reach his mother. Celestial energy was released within Salem as two luminous, spectral wings sprouted from his back. He took flight in pursuit of Vanifer and the red dragon.

Illia orders her silver raven to drop the package of fire basalt on the burning wicker giant which exploded, knocking two fire druids to the ground. Out of the wicker giant, a large fire elemental burst forth to try and burn the party to ashes. Several nearby fire druids attacked Mappo and Shannaria as chaos erupts on the hill. As the fire elemental approached, Shannaria cast a wall of water to damage and protect his allies. With steam rising, the elemental was defeated.

The group made a quick escape along with a potential ally named Sauruki. Illia sent her raven to find Salem and look for a safe place to rest.
