Vishaneh Amberglass (pronounced vee-SHAH-nay) is a glass mage in Heskalifos and resident of Tharios. She is one of the mages testing Kethlun Warder's magic. To do so she asks him to blow a glass globe, which turns out to be the first globe covered in lightning and later revealing the scene of a Ghost victim. However, she is unable to take Keth as her student because his magic is too exceptional.
She only appears shortly as a minor character in Shatterglass.
