Astral Tower

The Astral Tower is the central structure in the Astral World. From within its walls, Eliphas rules the world. At the top is a room with ornate pillars and it its center is a throne, which features a larger version of the Emperor's Key on top.

After Astral was forced to retreat to the Astral World to due to the injuries he sustained from Number 96, Eliphas placed him in an Astrite stasis crystal atop the throne until he was prepared to overwrite his memories. Yuma Tsukumo eventually arrived in the Astral World to save Astral. Despite Eliphas' intervention, Yuma eventually reached the tower with the help of Rainbow Kuriboh and Ena. Here, Eliphas confronted him and they began a Duel to decide Astral's fate.

The residents of the Astral World were able to witness the Duel in the tower through Astrite crystal viewscreens. When Yuma eventually defeated Eliphas, he was taken to the tower's balcony, where Eliphas explained that the Barian World was making its move. From here, he sent Yuma and Astral back to Earth.
