Giving name to the earthberg, the Three Sisters are a trio of large, prominent mountains. The mountains are rumored to be homes to an actual trio of sisters: three elemental seers; each one claiming a different peak.
Going clockwise from the city of Jetsam, the mountains/sisters are:
- Ventis, Baroness of the Sky – Seer of paths and directions.
- Thera, Countess of the Depths – Seer of death and doom.
- Sigmis, Duchess of the Flames – Seer of hope, faith, and life.
