Collected from Arsaga:

Of course, it's bizarre in it's own right. It's a helix, winding up into the night sky, with a segment of a double-helix at mid-height, that second helixoid - arcing across the distance of 180 degrees, center pointing straight out towards the sea - pulsing with light. A lighthouse.

The top platform is technically open to the wind, except for a shallow but domed glass roof, held up by levitation. There's a café in the helix near the platform, and small tables and chairs are up on the platform, making this a nice meeting place at night.

Conveniently, the pokécenter is just beside the pokégym - latter which is set into the foot of the Helix Tower, at its height looking less like a building and more like an exotic plant made of ivory, having structured walls spreading out like tendrils and leaves towards their end, peeling back from the main helix in fake organic ways. Ah, yes, the Glint Badge. When they're done staring at the city, they should probably head back down and organise themselves that one.

The inside of the helix is full of modern art that they've seen much of on their way up, as well as a conveyor belt like escalator leading all the way down. It takes its time, but there is no elevator to speed things up. The Helix Tower is primarily pokégym and lighthouse, after all - and beyond that, mainly a work a art. An escalator would simply not fit.

[There is a] strange vertical cut in the inner shell of the bottom of the helix - the entrance to the pokégym, like a black slash across those smooth ivory walls.

And it isn't just dark in here - it's pitch black. It's nothing one particularly wants to enter further into - the sparse light filtering in from the Helix does nothing to make the texture of the ground or walls any more palpable. It's like a huge, inky void.

As the other three enter, hovering near the door, peering into the darkness, a sudden light spawns not far from them. It's a spherical ball, set upon something conical, like a torch, except that the bottom tip of the cone grows from the ground, [emitting a warm glow].

The arena was huge, that much was clear - but that had left little place for the area of residence in the background, and it was a strange, crescent-shaped area, mostly spartanically designed, with the coolness of the city. Fortunately, though the light there is mostly dim, Naomi doesn't seem to live in darkness in her spare time, so there was at least some shred of normality there…

And, of course, Flash lights up the room [in the pokégym], exploding through the darkness and forcing it aside - and reveals a strange, but fortunately mostly simple room, tiled, with some of the same padded… so that's why the jumps had been so silent. More interesting are the platforms suspended from the ceiling, at size of one tile each, one square metre each, at different elevations, all softened, too. Even without the benefit of quiet landings making locating impossible, this setup was… different.
