User blog comment:GOTHICDEATH/Imperial Heralds/@comment-4158700-20151014225517

To put my two cents in - the reason there isn't an Imperial Heralds is because, though there is some decent background info, we don't have a picture portraying what a Legionary of the early XVII Legion looks like or their former heraldry (if any). The Word Bearers article hits all the main points though. Go over and check it out when you have the chance.
