Well, I guess thats it for this series. Thanks to everyone who read, laughed, and reviewed, and thanks for not reporting me for crimes against music and the Imperium.
A big thanks to Shadownja and TheMonkfish in particular for all the help, and to everyone who reviewed to tell me who I missed out.
Thanks again, and I hope you enjoyed it.
