There is always an air about departures that begs to be hidden. Whether it is fear of loathing or that of longing, neither of these emotions should play a role in a Forsaken's heart or mind.
Indignity may not be the oldest of the Spine, but he is surely the most brittle. Having mused over this subject, his decision is sealed - to prune a tree is to help it grow. And Spine certainly is growing with surprising health. As a humble priest, he feels that guidance is more required among the weaker guilds of the Horde.
To those he has not said farewell - be vigilant, and make the Lady proud.
Power to the Forsaken, Spine!
