Hama

Master Hama is Ivan's older sister and is a Jupiter Adept as well. During the first game, she ran the Lama Temple near Altin. Isaac's party met her in her temple while in pursuit of Saturos and Felix, but Ivan did not recognize Hama as his sister, nor did she reveal it. She later abandoned that post to leave for Contigo, her original hometown, and provide advice to the party there.

When Isaac's Group gets to Contigo in The Lost Age she reveals to everyone that she is Ivan's sister.

There is often confusion as to whether her name should be spelled as "Hamma" because the two games use different spellings ("Hama" in Golden Sun and "Hamma" in The Lost Age).
