This was something I dug up recently. Originally it was supposed to be material for a sequel to Telcontar Restored (Children of the Tuatha in the compilation) but rejected in favor of The Lay of Imladrien and Tinuvion and Swan-Song. Killer Parakeet's eating habits do make it into Swan-Song though.
As far as the Shadowhawk/Morgenstern story goes, I'm pretty much standing alongside a graduate student taking her qualifiers and learns more about her fey roots while another graduate student is trying to finish his dissertation but is haunted by not only his fey roots but also an oath he had sworn years ago and a mysterious creature with suspicious motives.
