Calliope Horn
Calliope Horn is the receptionist at the Teras Terrace branch of Pretorius Technologies. While she does her job efficiently (though it's made somewhat easier by the fact that the branch gets few visitors), she is something of a gossip, often using her multiple mouths to reenact multiple parts of a conversation at once.
Calliope has an acute sense of smell, which could come in handy in the unlikely scenario that people try to sneak in past her or bluff their way by her in disguise. She likes to be surrounded by a variety of aromas, and covers her desk with fragrant flowers, burning incense, and other strongly scented objects... not all of which have odors pleasant to the human nose.
