Calliope is an archeologist specializing in music and played by Jill. She's known Jaimus McNulty for years now as a consultant and sometime "finder" of artifacts. Calliope's speciality is the people known as  The First Men, their cultures, history, etc. She has advantage on History check in this area. 

In her earlier days she studied musicology with Professor Marius and as her capstone project she wrote the an operatic piece know as "The Songs of the First Cycle" telling the story of how humanity was created by the gods and favored by them. Little did she know, her professor was to rework these songs into something shadier, more cynical and well... discordant with the truth, because he claimed credit for this work along with another student Antiope Shadowsong. Their careers took off and Calliope tried to fight back, she was bad-mouthed and nearly driven from the community.

Since then, Calliope took up the study of The First Men and has become one of the foremost authorities on them. Too bad these academic studies are ignored by the public who favor the very popular, if corrupted works of poetry and musical fiction stolen from her.
