Abamulan I (born Aba-Mulan Feliza Yavona Sagisma Nalinbura; 1597 - 1670) was the first Queen of Vicus from 1635 to her death, co-ruling with three kings: her husband King Avab I, her son Toivan I, and briefly her grandson Eskander II. She was one of the most powerful queens in Vicusian history. A devout Zascaic throughout her life, Abamulan helped strengthen the Zascaic Temple within Vicus; a move which would come to define Vicus as the sole vestige of Zascaic power.
Abamulan was the daughter of the deposed King Sagismar II Nalinbura and his Moshabian wife Feliza. She married Toivan the Elder in 1619, and they had two sons, including Toivan. After his assassination by her brother Sagismar the Younger, she remarried Avab of Nalkhate, cementing an alliance between the two loyalist triumvirs. When Avab became King of Vicus in 1635, she was given the newly-created title of Queen of Vicus. In her role as queen, she co-ruled with Avab, assuming vast autocratic powers. When Avab went to war in Koltara in 1645, she ruled Vicus alone. Despite ruling as an autocrat, however, Abamulan was popular among the people for her numerous charitable works and construction projects.
Following the death of her husband in 1659, she continued to serve as an influential confidant for her son King Toivan I and his son King Eskander II. She died of natural causes in 1670.
