The Treehouse itself looks shoddy, but is surprisingly well-constructed. It is stationed on a difficult to access cliff edge overlooking a beautiful jungle. With the obvious exception, the place is considered off-limits to humans.
Surosâ brothers, HĂ€kke and Omolon, are buried there. Because of their respect for Suros and Radegast, they are enemies of Weyloran and her clan.
With the seven listed as the primary caretakers, the Treehouse has taken up a mantle as a sort of "Pokemon Bed & Breakfast", providing shelter and care for other wild Pokemon who need it- oftentimes for trade for either materials or labour in order to maintain the Treehouse. Most often, the ones who utilize the services are those who have come under the glare of Weyloran and her clan.
THE CARETAKERS

The Butler
He is aware of Radegastâs lineage, and fancies himself a servant to the family. He is not officially a butler, however, but this devotion has proven strong enough to make him the de facto leader of the Treehouse. He is comically immune to Jolderâs advances, though that does not stop her from trying. He speaks not unlike a stereotypical British butler. (_Author's note: I couldn't find a good image of a shiny Dartrix so this'll have to do)
He idolizes Radegast more than most. He keeps it under wraps, but finally meeting the boy has put a spring in his step.
Abilities: Overgrow and Long Reach. Also comically oblivious
Moveset:
-Razor Leaf - Throws leaf blades like throwing knives.
-Pluck - A savage jab with his beak, quick enough to pick pockets and steal another Pokemon's hold item.
-Synthesis - Absorbs sunlight to regenerate damaged tissue. Effectiveness varies by weather.
-Leaf Blade - A much larger leaf blade, utilized like a katana. Jakob is pretentious like that.
-Astonish - Boo.
-Foresight - Can read an opponent's moves to negate any evasiveness. Also allows him to see the physical properties of a Ghost-type so he can hit it.
Hold Item:

The Seductress
Her pheromones are often used to negotiate⊠well⊠just about anything that the Treehouse needs to negotiate. Sheâs got a âheartâ for pretty much anything, and especially loves to tease males. Her ultimate goal is to break Jakobâs obliviousness to her wily charm. If her hiss were any more sultry, she'd be constantly inflicting Infatuate.
Abilities: Corrosion and Oblivious
Moveset:
-Captivate - Essentially hits on her target. Sharply reduces the target's Special Attack

The Brain
Escaped the computer world with Radegastâs help. After parting ways, Doc met Jakob, and decided to stay with the Treehouse. Heâs the smartest of the bunch, but spouts off a whole lot of nonsense about âfactsâ and âcomputer lingoâ. Heâs capable of hacking into the toughest of human systems.
Speaks matter-of-factly, and often with suspicion, playful or otherwise. He's a smart cookie, that's for sure.

Moveset:
-Tri-Attack - A synthesized energy blast of flame, electricity, and ice. Has a chance to burn, paralyze, or freeze the target.

The Hippie
Lazy, spouts off nonsense, sometimes wisdom, but his psychic ability is no joke. Heâs often lounging out on the treehouse deck. They say Alakazams have an IQ of 5000, but youâd be hard-pressed to imagine this one is anywhere above the double-digits. Jakob and Thoth have deep respect for him, however.

The Refugee
Originally the power source of Project Siren, now lays low with the Treehouse. Jakob has proven to be someone she can trust, despite Doc Holidayâs knowledge of the Project. Due to her experience, she is difficult to make friends with.
She would never admit it aloud, but she is very grateful, and even a little fond of Radegast.

THE LAYOUT
The location is covered from the elements by an enormous slab of igneous buildup, forming a natural umbrella-esque roof over top of the small plateau. The only entrance into the cave is the natural opening with a wonderful view of the Akala Lush Jungle.
The climb takes approximately five minutes for an experienced climber even without equipment. It is rather like climbing a tree in that sense.
When one enters the cave, on the right is a clearing, where several metres away, the three markers lay undisturbed. To the left is a rather impressive structure of bamboo, thatch, and synthesized beams. It is a large, two-story house that takes up nearly half of the plateau, and also stands from floor to ceiling. The house has a kitchen with a synthesized potbelly stove, multiple pieces of furniture similarly made with bamboo, wood, and synthesized reinforcing elements. There are multiple rooms containing beds of many types. Most of them were built by the "Caretakers" after the Lord-Regent had gone off on adventure. Next to the kitchen is a pantry, containing Never-Melt Ice used to preserve the multitude of berries that are always stocked-up for the purposes of the Bed & Breakfast.
Upstairs, at the end of a long corridor, is a room with an untouched human-sized bed accompanied by an end table and an "imported" human chair. Above the bed, a crude drawing of the Reginald Coat of Arms is pinned to the wall. The drawing appears to have been drawn by hands covered in feathers. Few go into the room, mainly because the wild Pokemon who do visit are usually busy interacting with the other wild Pokemon who visit, as well as the Caretakers.
Several closets throughout the house contain assorted gear appropriate for the placement of said closets (eg. cleaning supplies near the stairs, cooking supplies near the kitchen, scarves by the door, etc.) Overall it is a surprisingly well-organized human house, only no human has ever been there save for the one who founded it.
Despite the nature of the location, the cave is actually pleasantly cool even on a hot day. It is also highly defensible, and the structures are reinforced and supported by redundancies to deflect any emergency- namely what would happen if the umbrella-esque slab of rock were to break. The place is surprisingly fortress-like in its structure.
Most importantly, in the far back on the first floor, is a shrine. The shrine is a simple pedestal, upon which a withered Dragonite antennae rests. The accompanying plaque and surrounding artwork of varying mediums depicts the atrocities of Demonbreath, in the hopes that history shall never be repeated in Alola or the world.
