[Added] [Map] Buried Takish'Hiz: Empire of Antiquity
 

Here is the code for the new contested dungeon and the new image it requires. Most of the referenced images already exist from other dungeons. As a bonus, this also includes the new Takish'Hiz themed guild hall.

The Gateway region with its 8 branching hallways is somehow a different in-game size than the corresponding region of the original image, so an extra sub-zone is added to handle it. This secondary region (though first in the priority list) uses the same image but a different zonerect and availablerect to handle it.

There is still one spot where the Gateway and Exchange regions overlap, causing the wrong map to be shown in some cases. It is an incredibly small region in the northwest side room (and only the far western edge of that room) of the Exchange where the Gateway map will be shown instead. Given how close these two regions overlap, even a sub-zone approach may not be feasible. The wall is nearly paper thin, and a clever Mario speedrunner could probably glitch through the wall.

The Exchange and the Biome overlap with one hallway that physically connects the two regions. The hallway originally existed in the Biome's image. Rather than dealing with yet-another-zonerect, I simply copied the hallway into the new Exchange image. This means the hallway appears in both maps, but players standing in the hallway will see the Exchange map. This actually suits the look-and-feel of the zone quite well, since the portal in that hallway is labeled The Elddar Exchange in-game (and not Blooming Biome).

There are also two spots of the Contested zone that are within these zonerects, but have no image. They are small rooms with no hostile mobs. I can add these rooms by modifying two of the original images, but they are also small enough that players shouldn't be getting lost.

Nice work.
Who is the zone in map?
Any order i should sort them in ?

The zone-in is in Takish Badlands. Gateway is the first room players will enter, followed by Exchange and Biome. I'm not sure on the order past that. There is a strict progression, but I didn't get far enough in the questline to see what that was. Gateway also acts as the transport hub. Players won't likely go directly between the other maps.

Should all Buried Takish'Hiz zones be in Takish Badlands ?

Only the Contested zone is off of Takish Badlands. The other three instances are all off of Raj'Dur Plateaus. I think the raid zone is also Plateaus, but I'm far from gettinga ccess to that one.
