I've been amassing them slowly over time and now with a deadline for a mates stag weekend of gaming at Warhammer World i have the time and impetus to get them table ready. Im building at painting this army in manageable chunks and this is what i have completed so far:
30 Infernal Guard Ironsworn
Infernal Guard Castellan
I figured i would start with the biggest unit in the force, the 30 Ironsworn, and then use the spare champion model from the command pack as a Castellan.
Next up will be a couple more heroes with a Bull Centaur Taur'uk (My General) and a Daemonsmith wizard.
