Lighthall is located in Cloud Mountain up near the Village Green. It is an octagonal room with stained glass windows, created by Luthe Glazier. Its entrance is a dim narrow hallway ending in light, and its interior is round with wood walls that are set off by ten multicolored glass windows of incredible height. The windows feature scenes depicting the tale of King Jupiter and his heir.
It is the location of the Cloud Mountain initiation ceremony, which is held to allow relative newcomers to Cloud Mountain to become members of the secret citadel.
Shows the victory of the Red Valley War against Garlacks, the wolf king.
The center circle of the window showed "Jupiter's crossing," a clearing between two woods. It was filled with hideous birds: Hawks, Eagles, Owls and Falcons. In the center an enormous blackhawk loomed over the form of a brown rabbit with the Fire Crown on the ground beside him.
The Top section shows Garten and Morbin looking down on the fallen King while Garten bends to pick up the Fire Crown lacking the Green Ember.
The bottom image of the window was the burning wood homes were destroyed and rabbits fled in terror as birds swooped in and wolves attacked.
The middle image features a vision of the mended wood. The top panel shows Smalls wearing the Crown of Flames complete with the Green Ember. In the events of Ember Falls, this window is broken by an arrow shot from Bleston's followers.
