When I started the Word Bearers I picked up the Heldrake kit. After stabbing myself numerous times with various plastic blades that model has attached to it I ended up getting some paint down and everything was going well. I manged to get it to this stage and then promptly fell out of love with the model entirely. 

Something about it just didn't work with the Word Bearers... Daemon Engines are for the Iron Warriors and the like... Then I realised what I should do. The Word Bearers would use Deamons pure and simple. So With that in mind I started hunting for a valid kit to use as a Dragon/Daemon.  After a short look around the GW site I decided on the Terrorgheist and I knew it was the winner.
