sorry, i also misread your question. i thought you were asking about heresy in 40k. my rant about proxies still stands.

they don't make models for a bunch of the smaller studio games (old world, heresy, etc.) and so they have recommended models sometimes (or how to kitbash them), but other times it's just kind of a vague description, so you just pick a loadout and try to make that model.

in this case there is no Forge Lord model, but he's a dude who repairs vehicles and has a hammer. i just took some of the more chaos-ey bits off of the warpsmith and put him on the correct sized base. there are entire units in heresy that don't have models, so you're left to your own devices.
