Black Templar chaplain, Grimaldus, with his retinue compliment. This model originally came out in metal (this set is) and then came out in finecast.

Character background (From Lexicanum, http://wh40k.lexicanum.com/wiki/Merek_Grimaldus):

The Chaplain was raised from his Marshal's Sword Brethren and inducted into the mysteries of the Reclusiam after the Battle of Fire and Blood. Such was his faith and devotion to theEmperor that the Chaplains saw in the young Grimaldus the making of a powerful warrior priest.[2]
He took his vows before the broken Sword of Dorn aboard the Battle Barge Eternal Crusader and has since justified the Chaplains' faith, zealously leading the warriors of the Black Templars in battle.[2]
