Not What YOU Might Call "Fun"...
It starts as a normal day at YJLA headquarters.

Most of the team is already present; there's a meeting due to start in about half an hour and a training session after. Only minor beeps and alerts are coming through over the computers, nothing that can't be taken care of by local law enforcement. Outside, it's sunny, and there are even birds chirping and twittering to each other. It's almost blissfully quiet.

Until, very suddenly, it's not.

There's a near-tangible shift to the atmosphere as a wave of something blooms from somewhere within YJLA headquarters and travels outward through the building. It passes through walls and furniture and people with equal ease, bringing darkness with it as the lights go out and electronics abruptly fail to function. Openings to the world outside of headquarters -- doors, windows, escape hatches -- are consumed by the walls around them, vanishing entirely in some cases or scarring over as if they were old wounds. The emergency generator hums to life for a moment before it too fails and plunges headquarters back into darkness.

A glowing fog begins to rise, barely enough to see by. It's purple, and parts of it glitter. Faint, abstracted laughter floats down the halls; and Alina's voice trails after it like a handful of ping-pong balls down a staircase:

"That's more fun."
