Carved Gates

The "Carved Gates" are a set of gates covered in carvings that Max's soul saw after he died.

History
After Max's death, his Death Reaper took him to these gates, which were in the middle of a barren desert. Right after, Khi's Fae form hand took his soul back to his body. These are probably the Gates to the Luminous Netherworld that Khi saw.
