Forge World has started taking orders for their next Primarch model, Lorgar of the Word Bearers.
From the announcement:
Lorgar, designed by Edgar Skomorowski, is an incredibly detailed multi-part resin model armed with Illuminarum and clad in the Armour of the Word. The newest edition to our Horus Heresy Character Series, Lorgar stands atop a scenic base depicting ritualistic trappings and inscriptions.
Rules and background for the Primarch Lorgar Aurelian and his Legion can be found in The Horus Heresy Book Two: Massacre.
