These are the messengers of Shadowmasters, who cross from the Shadowrealm to communicate with their confidants, eg. the inner circles of Smugglers. Golden Saints often bear gifts to their worshippers, and seem so saintly in their allure, that it is very difficult to confront them and not be awe-stricken. They travel through Tannhauser Gates and are impossible to either track or capture in that form. When defeated, they teleport back wherever they came from.
