This is the study and research of names (onomastics) and devices (coats of arms), helping people register their personae (the medieval person that they are acting as within the Society) names and devices with the College of Heralds.
This is calling announcements at events - so we can all forget our phones for a while - and heralding tourneys, announcing the progress and the victors to the assembled crowd. We also use heraldry to decorate our halls, fields and equipment, from tabards to chests to thrones.
This is running formal courts effectively and enjoyably, getting business done and adding to the pageantry of the scene. Here you become the voice of the Crown, making the day very special for those you call upon.
For heralds taking registrations: heraldic receipt
