I've posted up on
my blog my take on the Servants of Ra. As well as the usual suspects it includes Iset, high Priestess of Ra, and some of the fanatical followers she has recruited in Egypt and the Sudan.
In addition to the background in the book:
Akhenaton can further count on the high priestess, Iset, who claims to be a direct descendant of the high priests of Aten at Karnak. As such, she is the guardian of much secret knowledge that has been passed down from generation to generation over the millenia and has been instrumental to Akhenaton in his attempts to locate the regalia of Ra. She has also been tireless in her efforts to restore Egypt and the Sudan to the old gods and the glories of the past, recruiting many fanatical followers to the cause. She relies mainly on her mystical powers in battle, though she is not averse to using her poisoned fighting knife when needs be.
