One of my first original contributions to Diablo 4's Seasons was the "Sandy" version of the Mage Halls, to support the Seasonal narrative of Ayuzhan and Zotun Kulle's lost research laboratories underneath the Kehjistan deserts. Rifts in the ceiling allowing sand in and Demonic growths are both due to Malphas' influence and corrupting of "the Loom". These are just a couple scenes of the entire tileset.
I want to thank Lloyd Price for all his hard work with lighting the Sandy Mage halls - It wouldn't have happened without his hard work.
