Tis is a Thief and the daughter of the leader of the Thief Guild.
She is forced to make an income by hiring adventurers that would travel inside the Pyramids (which are already infested with monsters) after the Thief Guild becomes inaccessible due to the release of the mummy of King Osiris.
Out of money and desperate, she tries to steal from people, until she was caught by Iruga. After telling her story to the party, they decide to help her navigate through the Pyramids.
