Casey looked around frantically as he landed near the warehouse and stumbled over toward the nearest building to rest against it. His chest rose and fell quickly with each breath, and his pupils were wide, making the sudden change in lighting all the more painful. After a few moments, Casey dared to rest his head against the side of the building, trying to catch control of his breath. It was difficult to do so, he found, the longer he stood here with the pain quickly reaching a point he could no longer ignore it.
Casey removed his hand from his abdomen and winced at the sight of the blood. He quickly pressed his hand against his abdomen as firmly as he could and set his eyes over toward the warehouse. It seemed so far. Too far, even. He could apparate, but he would risk further injury due to lack of focus. Drawing a hissing breath, Casey removed his left hand again from his abdomen and quickly brought his right over to grab his wand then returned the pressure. He fumbled to gain a good grip on his wet wand before finally sending off his patronus to the warehouse with a message.
Lucy... Shed... Need help. Hundred or so yards from there. East.
