The background for the assassin is weird.
1. Inquisitors are trained in Schola Progenium http://wh40k.lexicanum.com/wiki/Inquisitor
2. Assassins are practiced in Temple from a very young age. http://wh40k.lexicanum.com/wiki/Officio_Assassinorum
If we said that he was first assassin (10 years of training) and was then selected for the Inquisitor OK but:
3. Death Cult Assassin are an extreme cult where some fall to Khorn.http://wh40k.lexicanum.com/wiki/Death_Cult_Assassin
4. The appearance of Assassin's character from Callidus Temple, but sniper rifles would make sense at Vindicare Temple.http://wh40k.lexicanum.com/wiki/Vindicare_Temple , http://wh40k.lexicanum.com/wiki/Callidus_Temple
Would not it be better to write the background so it is Inqusitor who was taught by Assassin in team and snipers, Xenos team members? Something like Ravenor and Eisenhorn when they learned fencing from Arianrhod Esw Sweydyr?
And the animation of those hair is also quite disturbing. Maybe I would not hold so strictly to the appearance of Callidus assassins.
Excuse my English. It's not very good, so I used the Translator
