Aieso is Grandmother of the Edi at Najida village. She is described as short, like most Edi, and plump.

The Edi are matrilineal, and they look to their oldest women as their leaders. Aieso is one of these women, and the one who Bren Cameron and Lord Geigi deal with when Ilisidi proposes to elevate the Edi to a lordship and a seat in the aishidi'tat in Shejidan, as of the events in Deceiver.
