I thought of this one myself. It sounds like Palace, but I didn't want to write it that way, because that was too easy I figured.

Pallas Athena is an epithet of Athena, the Greek goddess of wisdom. The Pallas part's meaning is disputed. It apparently comes from the name of another person, either a friend, rival, relative or other being who Athena accidentally kills. She then takes the name Pallas for her own, in remembrance or guilt, depending on the story.
