I don't have any real proofs about this.

We know there are three canon hosts, Action, knowledge and foresight. Maybe also Ender was a host, or maybe the heart.

Action knowledge and foresight are the three most important aspects for a Minecraft's player. Maybe the heart (friendship) as been corrupted by the evilness (but I don't know because it seems like the heart himself is the evilness, and it seems to be the heart of ender), but there are other aspects of a Minecraft's world:
Perseverance
Ingenuity
Creativity
Justice
Freedom
Adaptation
Exploration
And more

We know Juju has an oddities shop where she seems things that usually are coursed. We know from the animation that Gus had throw some keys to a pile of clothes, and then shade comes alive. I think that keys have been sold by the oddities shop

I guess collabs aren't canon (except musical collabs) and merch, or old things that contradict something new. Then I guess kinda everything else is canon. (And I hope here Game Theory is wrong)

In some grom's voicelines we can hear someone talking by his walkie talkie, and I think there are two options:
It is R-T. R-T watch the entire starr park from the cams, and Grom is a security guard, however the voice doesn't seem the R-T's one, and in one of his voicelines we can hear again the same voice from the walkie-talkie, which says to fight back.
It is the CEO of brawl stars (not Edgar)
It could also be some other not-brawler, but I don't think so

To begin with, I believe the Ancient City was built shortly after the war with the Piglins, partly as a defensive measure against a potential new conflict.

Regarding the entrance, I don't think there's much doubt: it's simply an entrance.

The City Center contains both the Redstone room and the Portal. I believe the Redstone room was a sort of laboratory for experimenting with Redstone, but they hadn't found a use for it yet beyond lighting lamps and opening a single door. As for the Portal, it seems to be related to the Well of Fate, though its exact destination remains unknown. Interestingly, in the Minecraft Dungeons 2 trailer, it appears to lack the Reinforced Deepslate.

Then there are the walls, which come in two types: The outer walls are wide, open, and covered in wool. To get on them, you have to enter from the start or climb two blocks. I think they would be useful against small-scale invasions: if a group of Piglins attacks some citizens, the inhabitants can jump onto the walls and escape on the wool. Meanwhile, the noisy Piglins would be obliterated by the Warden. The inner walls are narrower and harder to access. The entire population could gather inside them to defend against a large-scale attack, with defenders on the walls and citizens within. If the Piglins managed to reach the walls, a few defenders could hold back the entire horde due to the narrow space, knocking the enemies down before they can cause significant damage.

Finally, there are the ruins. The first ones are the barracks. As the name suggests, they were used for military purposes. Armor could be stored here, and soldiers maybe rested here as well. Just like the walls, these structures feature narrow corridors that are easily defensible. Additionally, there is a miniature version of the portal found within them.

Then we have the Camps. They are made of light blue and blue wool, dark oak wood, and some even feature a campfire (which is theoretically still lit). These could be recent, but since they generate inside the Ancient City, their origin is ambiguous: they might be original, built over something else, or relatively new. They could have served as resting points for soldiers, outposts for traveling heroes, or perhaps the "base of operations" for a failed Illager expedition attempting to renovate and reinhabit the city.

The Ice Box. It was likely used for food preservation, specifically for meat. This allowed the inhabitants to gather high-saturation food in large quantities at once and then store it for an extended period.

The chambers were used for someone important, and in one of them, there is even a desk with a chest on top, three blocks high—the perfect height for an Endersent.

I believe the sauna had four main purposes: It heated the entire city. It prepared warriors for the high temperatures of the Nether. It was used for hygiene. It provided relaxation for soldiers after combat.

Then there are the Tall Ruins. There are two types: one resembles an outpost, while the other looks like a two-story house without walls. I believe they served both for spotting enemies (especially the first type) and as living quarters (especially the second).

Finally, there are several pillars, another miniature portal, and ruins that are simply too decayed to understand their original purpose.

Does it make sense?
