For my first HQ for my Grey Knights I decided to do a Librarian. I really like the Games Workshop range of terminator librarians but after checking my bitsbox I found a lot of parts to create my custom HQ.
On one of the Salute shows I both a set of MDF buildings from company Wargames Tournaments Terrain. Unfortunately plain MDF skeletons are quite boring so I decided to give them additional touch to make them more interesting.
I found two plastic knight on some flee market ages ago and recently I dig them out from the bottom of my terrain box. Because I'm in process of working on city style terrain table I decided to add them to the board.
