Ring 4: Greed, a huge open cave with deep cracks that drop down into the unknown. The river from the reservoir in Ring 3 flows down here. Crytals in multiple colours are present, ranging sizes from regular to gigantic. Many concrete ruins are scattered across the realm. The lobby is underground, below the largest ruins, which is an abandoned mineshaft, relying heavily on natural ventilation and crystals acting as both a heating and cooling agent. (Look up the EToH Wiki for Tower infos for Ring 4 or the comments for headcanons)

Ring 3: Gluttony, a huge open mossy cavern with a river descensing from the thick mist blocking the distant sunlight, creating a large body of water down below. The sustainable lobby is built near the cliffside, overlooking the view of the colossal cavernous lake. (check the top comment to view the headcanons or look up EToH Wiki for more infos about Towers) (also ignore music and don't listen to the voice lol)

Ring 2: Desire, mostly consisting of a openly vast flat forest plain with a large water crossing the middle, dropping into the cliffside edge where the bottom is hidden by an unknown mist. The lobby is perched along the cliffside, above the waterfall, with many hanging balconies descending further below (unfortunately I can't list each Towers here due to character limit, so look up the EToH Wiki on the Ring 2 page, or look at my comment for the headcanons) (also music and voice bad srry)

Ring 1: Limbo, where it consists of a group of sky islands floating way above the surface. The atmosphere is ethereal and tranquil. This Ring contains a wide range of towers which spreads fairly across the difficulty chart. The center island contains a sustainable lobby, equipped with ventilation, snacks, and other stuff. (unfortunately I can't list each Towers here due to character limit, so look up official EToH Wiki on the Ring 1 page)
