Ayesha al-Abbas

Ayesha al-Abbas was the daughter of Jid and Bibi al-Abbas, the human mother of Norse demigod Samirah al-Abbas and a one-time lover of Loki.

She worked as a doctor and had met Loki at the hospital she worked at. They eventually had a relationship and had a daughter together named Samirah.

When Ayesha died at Sam's young age, her parents Jid and Bibi took in Sam and raised her.

The Sword of Summer
Ayesha is mentioned by Sam when telling Magnus Chase that he's not the only one who has lost a mother. Whilst dreaming after being temporarily killed in battle practice, Magnus is encounters Loki and at one point, sees him lying in a hospital bed with Ayesha laying her and hand on his forehead.

Appearance
Ayesha is described by Magnus as looking like an older version of her daughter Samirah.
