5 Knightly Orders

All heraldry from here.

The Hollow Guard. Their sigil is that of 3 conjoined legs on a white field. Their armor is fused shut and completely hollow inside. Runes engraved into the interior of the armor animate the knights, binding the spirits of knights of other orders slain on the battlefield. Animals flee from their presence and their order is considered impolite to bring up in conversation. It is a secret order, consisting of volunteer knights sworn to silence.  

Order of the Broken Hearth. They do not have steeds. Their banner is an ashy gray field with a red bar dividing it vertically. Their authority begins and ends in buildings that have been destroyed and rebuilt after a fire and yeomen will often arson their own property to come under their protection in times of hardship. Fire pokers are their weapons of choice and calling upon them for service is considered heretical by the crown.

Crow Knights. They use war picks, hooks and wear crow feathers on their armor to make themselves look larger. Their sigil is a blue crow on a grey field. They are known for showing up to conflicts they have no stakes in and swaying the tides in favor of a seemingly random side. When they are slain, crows do not consume their bodies and they do not rot.

The Knight Guard of His Royal Majesty. By far the largest order in the realm, the Knight Guard is comprised mostly of nobility and foot soldiers that show valor in battle. Their crest is a silver dragon on a black field divided diagonally by a purple bar. They are not the best equipped but their training is more than passable. They are respected by the general populous. Their Knight-Commander has slain a dragon and wears armor made of its indestructible scales.

Satyr Knights. Their sigil is a brown goat on a green field. They are not literal satyrs, but are renowned for similar reasons. They each carry a set of panpipes and ride donkeys. They are immune to the inebriating power of alcohol and regularly attempt to see if that immunity is absolute. They are often hired as guards for the few legal brothels in the realm.
