Yellow light cuts through the shadow of the hallway. You step into the narrow beam, reaching forward for the doorknob. Entering, you survey your lab. The walls, covered in papers and graphs, welcome you. By now, the eternal hum from the air conditioning is music to your ears. Your housing units chitter with juvenile creatures ready for their daily check. Checking your to-do list, the words at the very top remain uncrossed: "Repopulate world with genetically diverse creatures", as it always is. With this mission in mind, you equip your pen and notepad, anxious for your day to begin.
