The Furnace - A simple Dungeon Core Quest

Hello, sorry for the waiting, but I decided to do a funny.
Meaning that I drafted the starting creature, spells and traps for each theme, which will be available at this link:
I'll use Notion to keep track of all the creatures and things, fully knowing that these types of quest tends to become quite messy with bookeeping and be organized is the only way to make things function.

So, now you are going to vote on one of the three top tiers of the last vote. Choose more accordingly to the feeling than the mechanics: even if the initial monsters aren't balanced, this won't means that they cannot become strongers in the future.
The three plans:

[X] Plan: Feed the Machine
-[X] [DUNGEON THEME] The Underground Factory
-[X] [TYPE] Natural Entry
-[X] [PLACE] Black and Blue

[X] Plan: legally distinct Hallownest
-[x] [DUNGEON THEME] Endless Hive
-[x] [TYPE] Pocket Dimension
-[x] [PLACE] White and Black

[X] Plan: Welcome to the Medieval Backrooms
-[X] [DUNGEON THEME] Liminal
-[x] [TYPE] Pocket Dimension
-[X] [PLACE] Black and White

You can only pick one. The vote will be open until I get back to work tomorrow.

Domoter: Land of Intrigues

Domoter is a land immersed almost everywhere in mist, reducing vision and making the roads, already dangerous due to monster presence, even more dangerous. Domoterians believe in two things: exploitation on the lesser and technological advancement. This resulted in the widespread diffusion of necromancy and its more younger sibling, deadcrafting, the art of fusing together mechanical parts and undead flesh. Failed experiment, which according to the laws should be disposed definitely, have an unfortunate tendency to vanish and find themselves in the countryside. Roaming necromancer who directly reject the Domoterian University doctrine are another issue that villagers, quite commonly, tend to face.

Fishermen villages near the cost tend to be faced with another problem: a humanoid race of acquatic creatures that the locals call "Bothniol" is responsible for raiding the coasts for kidnapping humans as food source. Some raiding parting penetrate the hinterland, looking for anything precious that they could use.

The political entity that claims the majority of Domoter is the Republic of Collenia: famous for the Domoterian University, it's the greatest city of the region, governed by representatives of the noble families of Collenia. As expected, intrigue and violence are common behind the facade of the progressive city and each of the families is looking for anything useful against their political rival.

The God of Domoter is called Nitphin of the Mist, the Unseen or the Bindless. As the everreaching mist, Nitphin is something hidden and that cannot be grasped and provides boon to its Adventurer that allows them to move without leaving trace and avoiding obstacles, hitting targets from where they don't expect or tricking them with illusions and diversions. The Adventurers of Nitphin rarely use heavy armours, investing in swiftness, preparation and precise strikes.

Cideter: Land of Stagnation

While Domoter is afflicted by its eternal mist, the light in Cideter behaves strangely: during the day, the light is equivalent to the one of the first hours of dawn, not quite day, but not quite night; during the night, there's still a faint trace of light similar to the last hours of dusk. This sort of eternal continuity, with no clear day or night, is also present in the culture of Cideter, who thinks that there are no begins or ends, but only gradation of being.

While the Domoterian God is more hidden (figuratively and literally), the Cideterian God, Untyx of Dawn and Dusk, Death and Life, it's present in the everyday life of its deeply religious citizien. While necromancy is also istituzionalized, the reason is different compared to Domoter: in Cideter is used for preserving for the eternity its most worth champions and not to create manpower for menial labor.

The Adventurers blessed by Untyx are paladins and knight, stalwart champions against the roaming beasts of Cideter: spontaneously reanimated corpses, bloabs of condensed light or darkness and "light" and "night" scorched creatures are some of the most common threats. Done in their heavy armours and followed by clerics, Adventurers of Untyx are difficult to take down.

Another faction that is trying to take the place of the Untyx cult are the vampires of the Lazarus' Dominion: considered heretic for their faith in the First Vampire Lazarus, they sometimes offer a protection more sturdy than the cults of Untys provide. Mortal servants, undead servants and newborn vampires usually roams Cideter, looking for something useful to advance their cause.

There isn't a unified political center in Cideter because the Adventurer Guild did his best to crush any political entity that doesn't respond to them. So, the government is fractured in various small parishes, leaded by their respective Older Priest, that in theory should cooperate with each other. But when the Adventurers are not closed, it's not unheard that the Parishes try to absorb their neighbor.
