The headquarters of the Kaisaayan's Demon Slayer Corps was a floating island inside a void dimension.
This classified dimension could only be accessed by opening the giant doors in the right manner. The same giant doors that allowed Eren and other candidates to enter the test grounds a week ago.
The void dimension was akin to a seemingly endless sea and the headquarters of the Kaisaayan's Demon Slayers Corps was only one among many islands floating inside it.
These large and small islands floated at considerable distances from each other inside the pitch-black void. This vast emptiness was a result of potent space-element magic, creating a seemingly infinite void that served as an intricate network connecting various locations across Labh Salem.
The islands, scattered throughout the void, represented different cities and regions linked to this otherworldly dimension.
