|This article is about the Ancient Sky Arena. You may be looking for Pearl's Arena or Cloud Arena.|
The arena is set floating around clouds in the sky, with a warp pad in the front of the structure, a four colored lozenge symbol of The Great Diamond Authority behind it; along with small circles (resemboling the Galaxy Warp). There are stairs left and right to the enterance. Most of the arena is in ruin, by only a few columns gone, as one half of the structure is completly destroyed near the center. Two more of the same lozenge´s is seen upbove the big one, an the pink diamond, is the only one crumbled a bit. As the stairs lead down to the middle arena; three statues of gems holding weapons are seen below. The first one on the left is wielding a sword while looking similar to Yellow Diamond with her gem on the chest, and a bodysuit similar to Garnet, the second gem on the right is welding a spear, has her hand over her chest. Her gemstone is where her nose would be just like Jasper's. And last the third gem on the far right has her gemstone on her forehead, wielding a mace while looking to be shorter with an alfro. There seems to be a fourth statue of a gem on the far left, but cannot be made out due to being completely destroyed save for the legs. Below at the ruined end shows hexagon holes which look like windows. Gem writing is seen on the columns next to the statues.
Pearl mentions that some of the earliest battles for Earth took place in this arena during the Crystal Gems' rebellion against Gem Homeworld. This was where Pearl first understood the concept of chivalry and what it means to be a knight; to be completely dedicated to a person and a cause.
- The four lozenges that appear on the back wall of the arena represent the Great Diamond Authority.
- It appears to have been made before the unknown (pink) member of the Great Diamond Authority was decided to be no longer represented in the lozenges, as shown on the Diamond Authority lozenges shown in the Gem Warship.
