There's a predator cult out there

When Arizona enters Reine City in Chapter 1, you can go into a house where the reindeer inside complain about scary noises in their basement, and one of them gives you the key to the basement assuming you're the person they hired to take care of it.

If you go in there you're immediately trapped by predators, and you end up discovering the basement is part of a larger underground complex. Going to the right first leads you into a room with a doll that's described as "really old," and continuing has Arizona enter the Reine City sewers.

Continuing upwards leads you towards the Altar of Appetence, which proceeds to open and out comes a bear and several other predators. You do canonically defeat them, but going up to the now-closed altar and interacting with it has Arizona mention concern over the fact she can't wait around for it to open again.

Later on in the Temple of the Ancestors there's yet another one, the Altar of Esurience, which has Arizona battle a similar set of predators and causing the altar to close.

Now, the AoE, while out of place thematically, at least seems to match the stonework and color of the surrounding themple. The same can't be said about the AoA, which has the exact same style but in a modern sewer setting.

Here's my theory: someone put it there not too long ago, and the same thing probably goes for the one at the Temple.

Think about it, the predators were banished at the very least over a thousand years ago. Reine City on the other hand has no records of being as old as that. If the altars were from the time predators got banished, the reindeer building the sewer system would've stumbled upon the AoA and either moved it elsewhere for research/display (they have a large museum of history and art, after all) or deliberately destroyed/buried it, they wouldn't have left it perfectly centered and positioned in a large spare room.

Texas' story has accompanying images, and they show ungulates opening a dimensional rift in the sky to banish the predators, there's no mention nor depiction of them using the altars to accomplish this.

There's also the fact they have morbid names that only the players get to see. They're not "mysterious altar" or "strange rock" or even "????", they've got concrete titles revolving around hunger.

Their locations are perfect for maximizing the carnage predators will cause once they escape. The one under Reine City is accessed through the basements of civilian buildings, and flavor text in the game's official site mentions the Temple of the Ancestors is a popular destination for archaeologists, adventurers and grave robbers.

Outside of sheep dogs (which are definitely not behind this) and maybe Fred, there's no confirmation there's any group of predators that are still around in Foenum, which means that, whoever put those altars where they did, were definitely ungulates. For what purpose? Who knows, maybe to convince predators to give them power, or some fantasy version of ecofascism, or maybe just plain old doomsday cult-esque beliefs.
