Seseong Guild building

The Seseong Guild building is located somewhere in Seoul, South Korea. It houses the majority of the Seseong administration's offices, as well as residences for Hunters and staff.

Layout
The Seseong building actually consists of two buildings which are connected—the older main building, and a newer 15-storey building.

Past the entrance to the guild building, presumably on the first floor, is a security check where visitors are given inventory-sealing bracelets. The interior of the guild past the security check is heavily guarded, with members of other guilds not allowed within. There is a reception area, however, where outsiders can wait.

The guild includes multiple amenities designed for Hunter use, such as a professional hair salon, exercise facilities, and a medical facility. There is also a kennel prepared for Comet, with a window at the front large enough for an adult Thorn-Winged Dark Dragon to fly through.

Sung Hyunjae's house
A mini portal connects the main Seseong building to Sung Hyunjae's house, to which Seseong's security chief and Sung Hyunjae himself possess keys. This portal leads to just outside the door to the house, which requires an additional key and has a doorbell. The door opens into a hotel lobby-esque foyer at least two storeys tall. Stairs lead to the second floor, which is open to the foyer. In the center of the foyer is a small decorative garden, with benches placed near it. From the ceiling above this garden hangs a cylindrical tank of colorful tropical fish; its glass is particularly clear, seeming almost nonexistent. This glass is likely a dungeon byproduct; its permeability can be controlled at will, such that objects can pass through it while other portions remain solid enough to hold the weight of a grown man.

The house itself is sprawling, filled with rooms upon corridors. There is a spacious room on the floor above the foyer, overlooking the tank, the top of which is set directly into the ground and covered with a layer of the same permeable glass. One of the rooms in the house acts as a sitting room, furnished with a table and sofas. The multiple rooms include some guest rooms which generally go unused. These guest rooms have soft beds as well as chairs; the intensity of the lighting can be controlled with a remote. The attached bathrooms are furnished with high-quality bathing products; hot water can be scheduled to fill the bathtub at specific times. There are also small living rooms attached to the bedrooms; the doors to the rooms open onto the living area, such that the beds are hidden from immediate view.

Security cameras are placed throughout the house, which Sung Hyunjae can access from his phone; these include a camera at the front door to observe visitors.

Rooftop garden
On the roof of the new building is a garden. Glass doors lead out onto the large roof, the edge of which is lined with tall trees, blocking the view to hide the altitude of the garden. Sculptures and fountains are placed among the grass and neatly-maintained flowerbeds, a small greenhouse is included, and walking trails lead throughout the garden. The garden is large enough and has enough visual cover throughout itself that multiple individuals can be inside it without seeing each other. The flowerbeds presumably feature a variety of flowers, including lavender hydrangeas.

There is a pergola at one side of the garden, under which is a table.
