The alien's curiosity was piqued as it glided upstairs, the tantalizing scents of sweet foods and succulent meats from the room below still lingering in its memory. However, as it ascended, a new array of odors assaulted its keen sense of smell–the unmistakable scent of numerous humans in close proximity. However, their overwhelming scents had barely clung to the walls and floors. They were new.
The alien quickly deduced that these humans were recent occupants of this dwelling, likely visitors like itself. Combining this revelation with the impressive spread of delicacies it had encountered downstairs, the alien arrived at a logical conclusion: a feast had recently taken place. Celebrations and festivals were universal constants across the cosmos, and the alien recognized the familiar signs of an extravagant achievement display. Food and treasure were often the centerpieces of such events, with music and dance serving as additional forms of expression.
As the alien reached upstairs, he detected more and more new human scents. The potential risks have risen, and so do the rewards. The parasite's senses tingle with anticipation as it tries to discern which chamber might hold the most promise.
The alien pressed its translucent body against the door, feeling the cool wood and flaking paint beneath its surface. A faint murmur of sleep-filled breathing emanated from the room, and the creature's hunger intensified. Keeping close to the walls, the alien's body adhered to the surface as it moved silently, its view from above allowing it to inspect its potential prey. The alien's advance receptors sensed the human's steady heartbeat and shallow breathing. Using the moonlight as his guide, he dipped slightly to observe his prey's features.
