Crownsguard

The Crown's Guard is the primary law enforcement of the Dwendalian Empire. As a hired and trained militia, they are sent throughout all the cites to keep the peace while acting as a national secret police that observes and eliminates any opponents to King Bertrand Dwendal's reign. Tensions brew among the common folk due to the chafing watch of the Crown's Guard.

The Crown's Guard in the Marrow Valley are trained in Bladegarden. The standard uniform and equipment of the Crown's Guard consist of vermilion/maroon robes and bronze scale mail breast and arm plates, a shield, greaves, a helmet, a crossbow, and a basic longsword.

He was described as having burly arms, a heavy torso, and very scrawny legs, and having a widow's peak.

The Traveling Tent of Curiosities Incident
Two Crown's Guard were standing guard during the performance of the Carnival of Curiosities. When one of the audience members suddenly transformed into a monstrous creature, they attempted to make their way through the panicking crowds that were fleeing the tent. After the commotion had died down and the creatures had been slain, Flynn sent his companion Sivelmen out to get back up while he tried to get a sense of what had transpired.

Left on his own in the tent with the party and the two zombie corpses, Flynn was visibly sweating and scared almost to the point of shaking. Having never had to deal with anything like that before, he tried to use whatever training he was given to deal with a traumatic scenario for which he wasn't actually trained.

Soon after, ten Crown's Guard entered the tent, among them a man who appeared to be the town's watchmaster.

Quickly taking control of the situation, the watchmaster questioned those present, including Gustav Fletching, whom he looked down upon with a general sense of disinterest and disrespect. Speaking on the behalf of the Starosta in appreciation for the party having dealt with the threat, he proceeded to leave behind five guards to detain the circus performers, while warning other parties not to leave town or face the consequences of having the full might of the Cerberus Assembly track them down.

After Yasha had led Flynn off towards one of the larger performer's tents to acquire Toya, she tricked him into entering it on his own so she could make a break for it and run off. Realizing the ruse, Flynn rushed back toward the main tent and informed the watchmaster of having been tricked. The watchmaster then sent three of the guards to go with Flynn out of the tent in search of her, with five of the remaining guards to chain and shackle Gustav, Bosun "The Breaker", and Mollymauk Tealeaf to the ground, after which they were dragged off to the stockade. The remaining party was informed to stay in the city until told otherwise.

The remaining guards were instructed to gather, begin questioning, and generally keep an eye on the performers, which they gathered together in the campfire common area behind the show tent. While four of them were in the process of doing so, they noticed Beauregard sneaking about suspiciously. Recognizing her as being part of the group that had been within the show tent, three of them proceeded to shackle and manacle her and take her to the stockade.

The next night, when the party had been investigating the events that had transpired and had made their way back to the carnival, Jester had been caught sneaking around by a guard named Damon, who had been sleeping in a chair by the fire in the performer's common area. Although she alerted him, she quickly cast Charm Person on him so that she could continue to sneak around without issue. Later, while Caleb had been looking through Frumpkin's eyes, he saw Kylre emerge from his tent and cause Damon and another guard to collapse onto the ground and bulge and mutate into zombie creatures. Dust and sand replaced what would be blood spilling out of their wounds as their flesh split and burst. The party dumped their burnt and carved up corpses on the edge of the Ustaloch's muddy banks.

After the party had found and defeated Kylre on Crookedstone Island and brought its head to shore, Caleb, with some difficulty, was able to speak with the lawmaster to come to the Loch Ward docks and examine the culprit "he" had slain. Although the lawmaster was in a mindset that he was essentially turning himself in for the murder of one of her suspects, she did follow suit to see the severed head.

During this time, Jester, Beauregard, and Nott made their way back to the Nestled Nook Inn to resume their "house" arrest. After a series of failed lies when they got caught, the group was taken in chains to the stockade. Arriving there, they were just in time to catch and be dragged along with Caleb towards the docks to see the head that Fjord was keeping an eye on nearby.

After the head was examined there was some discussion and some uncertainty as to the true nature of what the head had come from. Lawmaster Norda called for the aid of Archivist Xenoth, who soon arrived. With Caleb's Fiends of Folklore book serving as a reference, the head was determined to be that of a type of fiend called a nergaliid.

Alfield
The party encountered an injured Watchmaster Bryce Felid during a gnoll attack on the town of Alfield. The town suffered much loss of life and was severely damaged by fire during the attack. Bryce told the party that they had been with a group of four Crown's Guards that were exchanging volleys with the gnolls, and who were tending to their injuries.

Seeing the party approach, able-bodied with weapons at the ready, Bryce directed them to join the fight and promised to pay thirty gold pieces per gnoll ear. After the battle, Bryce paid the party 360 gold pieces.

Trivia

 * Matthew Mercer has stated on Twitter that he envisioned the Crown's Guard as resembling the army of the late Byzantine Empire (1200s to 1453).
