About a kilometer above Ulambus, there was a colossal circular building in the sky.
This circular building looked like an arena. Two intersecting rings of floating runes surrounded it and slowly rotated, making the entire building seem like a magical miracle as it floated in the sky.
This was the greatest masterpiece of the Academy's Silver City, the Sky Storm Altar!
In the beginning, the Sky Storm Altar was also known as the Cloud Temple or the Cloud Coliseum. However, because the kingdom of Erathia had gained the favor of the angels, it obtained the Cloud City Altar, which could summon angels. Therefore, in order to distinguish it from Cloud City in Erathia, Silver City changed the name of the Cloud Temple to the Sky Storm Altar.
