		"You can feel the panic start to rise in your chest as you pick up Sig and start scanning the room for a way to\n"

		"A creature breaks out from the pack surrounding you and begins to walk towards you. It stops less than five feet\n"
		"away and starts speaking in a raspy voice that sounds as if it hadn't spoken for some time and had spent that time\n"

		"and I don't suspect that we will be going anywhere anytime soon. Much like you we did not choose to inhabit this\n"
		"place and much like you we are trying to make this place our home.  In many ways we are two sides of the same coin\n"
		"and the more we ignore each other the more we will haunt each other's existence.\"\n"

		"comfortable space. The creatures peer in from outside the door and as you watch them out of the corner of your eye\n"
		"you can see a timidness in their movements, as if they are curious children looking in on previously forbidden area.\n"
		"This is a trait that you had not expected to find and your initial impressions begin to change.  Maybe you misjudged\n"
		"these beings. Maybe with some time you can not only find a home for yourself but help these creatures find a home within\n"
		"these walls as well.  Besides, it is not like leaving is an option.\n\n"
