As she opened her eyes, Nexus felt as though her head might split open, yet at the same time the pain felt very distant. A bright light shone through a hole in the roof of whatever structure she was in, momentarily blinding her. Disorientated she looked around for some clue as to where she might be. It was hard to focus with the room swimming and her head thick but she could just about make out a pastel pink butterfly mural pasted on the wall nearby.
As she tried to stand she became very suddenly aware of the blazing pain in her hind leg. Wearily she raised her head to look back. The floor around her was soaked in blood and puddles from the earlier rain storm were dyed a dark crimson. Blood still oozed from the jagged wound to her leg. 

Panic surged through Nexus and she desperately tried to stand on her three good hooves only to stumble sideways as a horrible dizziness swept over her. Trying to clear the fogginess from her vision, she focused hard on standing still and taking in her surroundings.
The room around her looked like it had once been some sort of reception. The white walls were stained and cracked with age and neglect. Here and there bullet holes had blown chunks of brick away leaving ugly craters. The glass front had been blown out long ago and the shattered glass was strewn across the floor all around. Light streamed in through a skylight far above through which Nexus could see blue sky and clouds. At the far end of the hall was a wooden desk though it appeared someone had once used it for cover judging by the splintered wood that traced along its length. Behind that was the damaged yet still oddly cheerful looking butterfly mural.
From the ancient equipment and mural, Nexus figured this to be some kind of hospital. Before passing out she must have been looking for a healing potion or bandages to treat her wound. Everything after the dash inhaler seemed to be a merged multi coloured mess in her mind that refused to make sense.

Gingerly hoping on her three good legs and trying to blink the darkness in her vision, Nexus began to make her way across the room. It was doubtful anything would remain unlooted but if she didn’t find a healing potion on some bandages soon she was surely pass out again. 
Crossing the reception was an agonisingly slow process on three legs, occasionally hopping off the forth to keep balanced. There was a terminal sheltered behind the shot up reception desk which miraculously still worked despite having both a cracked case and screen. The text was hard to read, more so with the burning pain and thundering headache but she just about managed.

Disappointingly, there was nothing worthwhile to Nexus unless she developed an urge to fill out tax returns on syringes. As she turned to leave however, another wave of nausea inducing dizziness filled her head and she toppled over, face planting the floor with a dull thud. It was from this position that something caught her attention beneath the desk, something small and silver. With a little magical manipulation. which did nothing to improve the headache, she drew out a small key with a tiny tag attached to it.

‘Store Room 2A’

Nexus could just make out the tiny writing scribbled on the tag. If this was the key for a store room, maybe it was still unopened? Either way it was her best and possibly only chance at this point. With fresh determination she fought her way upright and began limping towards the nearest corridor.
