The Clinic is a free-standing structure, comprised of an old hunting lodge later expanded and reinforced by early members of the Thistle Kingdom. It is bypassed by one of the main pathways into and out of the Ruins proper - as such, it is well situated along a main thoroughfare. The path is wide enough for a horse and cart, and is regularly used by such to deliver important medical goods to and from the building.

The building itself is roomy and has two floors, including an open upper level where emergency stores, such as blankets and food, are kept. The lower floor is made of stone, and is of original construction. The upper floor is made of pine, crafted by Luperci builders during repairs. It is on the upper floor where ill or resting patients are kept in narrow, simple bunks. There they are tended to by any of the kingdom's Curanderos or the Cleric.

There are three two separate bedrooms on the first level that have been converted for patients use. The bathroom and kitchen have been cleared out completely, with both now serving as storage. There is a fireplace in the main area as well as the kitchen itself. Outside the structure, there is a water trough that is cleaned every few days or as needed.

In August-October 2020, Argive Hemlock lead a pack project that brought about the construction of a root cellar. The cellar's purpose is act as a safe place to store additional dried herbs and other medicinal supplies for long-term purposes. It's dug into a small hill located within close proximity to the Clinic. Rocks and timbers reinforce the walls, and are also used for the flooring to help prevent erosion from foot traffic. The entrance is a simple, wooden door which opens into a small entryway before leading down to a short step of stairs. The room beyond opens up to a decent-sized area that is tall enough to allow an average-sized wolf. It is wide enough to allow for cupboards and shelving to line each wall without making the area feel too cramped or impeding individuals from stooping or bending over.
