Ilvani is the witch of Ikemmu in the Shadowfell and is the twin sister of Natan, the former high priest of Ikemmu. In 1479 DR, Ilvani was sent on an expedition to scout an area of the Shadowfell north of Ikemmu. Her party was captured by a Shadar-kai enclave and most of the members were tortured to death. Ilvani survived her imprisonment and was rescued by a group lead by the Ikemmu warrior Vedoran.
