You walk to the door of your friends house. Knocking on it twice, the door swings open immediately. You can see your friend Ryan, a protogen, standing in the doorway. Ryan: "hey bro! you came! come on in, my mom is fixing up some mac & cheese, and the other people are here too!" He grabs your arm, and pulls you inside the house. Looking around, you can see the house is a rather modest and advanced one, it even has smart features like circadian lighting.
