In the earliest days of the Erinos Clan, and indeed, echoing the date of many Mandolorian Clans before, during, and after the Fall of the Empire, many such who called themselves Mandolorian were cast down, scattered, or enslaved, struggling to preserve their culture, let alone their lives. But stories and traditions survived, and all across the Galaxy, the spirit of the Resol'nare preserved, as did the people who carried it. Remaining from one such battle for freedom and honor is a standard-fare shock collar, common wear for many slaves in many systems. This collar is rent open, its neck twisted and ripped so badly that one can still imagine the scream of the metal, and it's chain broken. Legend says that a captured Mandolorian tore it off his throat with his bare hands when he and his brothers were captured and made to remove their helmets and renounce their way of life to serve vile masters; close examination of the "artifact" however will reveal a more likely cause for the break to be from explosive force, possibly from its wearer choosing a more permanent and fiery freedom. Regardless of fact, it is the story that persists, and though useless in a practical sense, the Broken Chain, as the collar is often referred, is known as heraldry of defiance, tradition, brotherhood, and freedom.

Everything has been drawn by me, including the overlay (screen effect). In case the Aurebesh font is hard to read here's the text:
M.I.S.T.R.E.S.S "Beskar Fist of Justice" - M = Multiple I = Identifiable S = Small T = Trailing R = Rocket E = Electronic S = Support S = System

* Can be set to Stun
* Portable
* Can track Trajectory
* Heat Seeking

Unified an entire tribe of Mandalorians after taking out a Dictatorship in the Tratlaum System. In an inequal fight of 4 against 1, each of its 4 missiles ended the lives of the corrupted rulers, like a Beskar fist of Justice.
It was rumored to have been owned by the illustrious Mandalorian woman Zevennah Beskarfist

Title: Bone Lanvarok
Physical & Tech Specs: An ancient polearm lanvarok fashioned from the bone of a Rancor. Length is 2 meters and weight roughly 15 lbs. It is wider at the base and tapers towards the top where a mallet has been fashioned.
History: The Bone Lanvarok is an ancient polearm whose history is not entirely known. It has been passed down within Mandalorian clans and has been used as a battle standard since time immemorial.

Name: Beskar Battlelord Baton
Description: The Beskar Battlelord Baton is a trophy melee club for Mandalorian clans. It is made of pure Beskar and is shaped roughly like a night stick (perpendicular handle to a baton) so it can be held in multiple positions.
Story: During major training events or clan wargames preparations, some Mandalorian clans would create the Beskar Battlelord Baton as an award. The "Battelord" champion would receive this to carry as a part of their loadout or to display as a trophy. In tighter times, the Beskar would be melted down for armor or arms. However, this was seen as an extreme form of dishonor to the owner, the clan, and the name Mandalorian. The baton is a symbol of strength both in its composition and the reason it is given.

"The Fabled Stamper of Can-On"

Once lost amid a sea of stories that stretched over the course of eons, this fated object has been reclaimed by the Dark Council. In an attempt to bring order to an expanded universe of chaos, Grand Master Pravus and his Voice Evant Taelyan used the Stamper of Can-On to bring order and structure to the Brotherhood's political and visible narrative among the Galaxy at large. It is now entrusted with the Voice of the Brotherhood, and passed down through the line of succession.

Anything that bears the "CANON" stamp, by extension, becomes a true part of the Brotherhood. The ink is binding and definitive, making its power much more than meets the eye.

Unifying Symbol: Right Hand of Daggo Mouk
========
The severed cybernetic limb of Daggo Mouk - rather than the Ithorian's actual hand (sadly) - has become a unifying symbol amongst Brotherhood forces. Both a war trophy and icon, it represents the ability of the Brotherhood's disparate units to unite against a common foe and prevail.

Rather than actual fingers, two massive rusted pincers constitute the digits of the "hand," with the limb ending in a lightsaber burn left by the weapon that severed it from the Guild Master's harness. Many among Brotherhood clans claim to have made this final cut, yet none can explain why only one was seized when Daggo was known to operate a pair. Hagiography abounds, and while the mystique of the object is common knowledge amongst the Clans, it is undeniable that the rallying of Brotherhood forces around unlikely tales of danger and adventure to retrieve it have a positive impact on morale. Such bolstering is desperately needed in the ongoing battle against the Collective, and it is suspected that the hero truly responsible for claiming the limb has refused to come forward accordingly.

Perhaps, when full spectrum domination has been achieved, the truth of Daggo Mouk's hand will be revealed. Until then, it is a symbol of the Brotherhood's strength, whose presentation teases rallying cries from admiring souls.

Name: Star Chaser
Description: Z 95 head hunter. Painted solid black with the emblems of mando painted on the side.

History:This ship belonged to a Mandalorian mercinary during the early period of the empire. Known for his skill as a fighter pilot this ship gained a reputation as a symbol for the power and skill in combat of the Mandalorians.

Inspiration taken from Sunshot gun from Destiny 2 Video game, based on my interpretation of Idris/Xen's Westar-35 lineart.

The Ewoks have the best symbol of all! A lost 3PO unit's head that they found on the Moon of Endor. They have polished it and painted it with their tribe's colors and have worhsipped it ever since they met C-3PO. They pray to it for good fortune and hunting, and they hope that one day, the missing body will fin its way to the glorious head of the golden god! All hail the golden god!

Brotherhood Holocron:

The Brotherhood Holocron is a symbol representing the history and unity of the Brotherhood. The holocron has been designed to record and play information about the Clans and Leadership of the brotherhood. Appearance wise the holocron opens up into 8 pieces, 9 if one counts the center which stores and projects the data. The 8 pieces each have a different color and symbol, as 7 pieces are dedicated to the Clans while the last is dedicated towards the Dark Council and Brotherhood leadership.

"Crest of the Forgotten"

A symbol created by Zodac Polcim after the Battle of Jakku, it was made to represent the Super Star-Destroyer Inflictor and the Star Destroyer Ravagor, which are recreated in the triangular shapes within the symbol. The two circular bits, which lay outside the supposed Destroyers, represent the first and second Death Star.
The line that overlaps the symbols represents their destruction, while the red behind it all represents the Emperor. According to Mandalorian culture, Red honors the father, the Emperor the acting father and head on the Empire.

Name: Demise of Palpatine Flag

It soon spread and became the image for underground resistance to the Empire and the Emperor himself. Often found on flags, walls and anywhere it could be placed without being caught.

The Mask of Momin

This mask would represent a return to the old ways of the Sith. When the Sith were a power that could conquer entire star systems. Under the Rule of Two, the Sith Order crumbled and weakened, because it is not the nature of Sith to train an apprentice to one day replace them. We hoard our power and it must be wrested from us by someone deserving, someone able to take it. Under the Rule of Two, and the philosophy that it propagated, the Sith became more focused on galactic domination and the eradication of the Jedi. Momin's philosophy was that everything we do should be in service to the Dark Side of the Force and through our service, the Dark Side would grant us the power we so desire.
