Whenever a group member, or the group is tasked with breaking and entering (or if they're just doing it for fun, hey! :D ) this song plays!

Actually, that's a lie. There will be a few stealth dungeons which have themes of their own, but for those that don't, this theme is a good fit!

This song is first heard in Season 1, when the group needs to sneak into a heavily guarded castle to meet someone important.
