The Ehqaj City PokéGym is both a building in Ehqaj as well as a maintained stretch of coastline, often doubling as an event venue and even more frequently used for people to spend time with waterbound pokémon without having to worry about tides, wildlife or the jagged rocks lining most of Sehto's shoreline.
Descriptions from Sessions
Collected from Arsaga:
The gym building is uninteresting, almost featureless from the outside, looking much like any other building in Ehqaj with one exception: the big pokéball sign stencilled above its front doors, outlines of the same lined with neon tubes that alight at night time, red and white. The doors themselves are smooth glass, though it's hard to make out precisely what is going on inside, despite that.
The inside of the pokégym is, surprisingly - for Nikki - actually not primarily meant for humans at all, or so it seems. Instead, there's a thin, tiled strip leading around a massive aquarium of sorts - that's why it was so hard to see anything from the outside, there's little else but the light-diluting water to be seen! And the plants reaching up from the base of the basin seem almost blurred. It's amazingly silent, though, with no dripping sounds, and no sounds of cascading water. The room - and thus, the aquarium - must be about thirty by twenty metres across.
Collected from N'Sehla:
Rain drizzles down from the night skies of the twelfth of November, 2005. A smear of light leaks from the Ehqaj City gym's milky glass doors, filtered through the tank of water from the depths of a building. Rose Kaiki sits on a bench, checking her notes for the day. She had a lot of preparation training to do for the upcoming harbour festival - schedule was tight about that.
Disturbing the silence of the early morning is a firm knock on the locked glass doors, tone vibrating through them until it strikes the walls, ricochetting from them and reaching Rose as a subtly echoed, chaotic, but muffled medely. Her glance snaps up, glancing toward the double doors almost with confusion. There's not much to see from where she is - even if the huge aquarium was not in the way, the world outside is darker than the interior, making any view out of those milky doors fruitless.
Redwood, her Ivysaur, follows her gaze with natural curiosity, right forepaw raised in anticipation of following his trainer to the doors. Without letting her gaze slip down to the Ivysaur, Rose lets her left hand's fingers drift down through the air into its direction. “You can stay if you like,” she says, though her voice betrays that sliver of confusion that she has from having anyone want her attention this early in the day. Slightly perplexed, having risen to a stand, she makes her way along the thin, tiled path wound around the aquarium.
The doors are meant to be opened automatically rather than manually - going against the tension springs in the frame to keep them open requires her hands stay on the edge of the door.
The Ivysaur gets a nuzzle of Rose's ankle in, in passing, before she's passed the pokémon, heading through the narrow corridor winding its way around the aquarium to the light switch near the back.
Neon lights flicker to life in the gym, illuminating the lazy swirls in the tank.
