This is a heartbreaking story, and in fact, almost every one of the Forgotten has such a heart-wrenching experience behind them. Being separated by life and death is one of the most painful things in this world, and the complex situation of undead creatures, where even death may not be the end, complicates a simple farewell into endless twists and turns that plague the mind. Nearly every story related to the undead is far more emotionally compelling than the everyday emotions of the living. For instance, the Little Loli from Dalaran County, unresolved love stories, the tragic story of the father, Zaken, and his daughter, or Mr. Ximen and... but that doesn't count.
For some reason, whenever faithful love stories are mentioned, I think of Mr. Ximen's majestic demeanor, which is quite bizarre.
