Not much is known other than the fact she received her training in Kirkwall to become a templar.
Moira is involved in Prime Suspect.
She tells Hawke that Emeric left not long ago, and that he said Hawke had arranged to meet that night; Hawke questioned this, stating he had done no such thing. She then hands Hawke a letter -- supposedly from him -- which Hawke denies. Moira states she knows nothing more of the situation, and dismisses it as a misunderstanding, stating Emeric has been acting strangely for months. After Hawke discovers the truth, Moira arrives and sees what has become of Emeric and suspects that Gascard DuPuis has done this.
