TLDR: Dwarves rule, elves suck
[sblock=Intelligence (History) 12]This story is for anyone who saw the head priest's thread-of-gold vestment, and made their Intelligence (Religion) 12 ability check. The vestment is a series of stitched-together panels, rather than one solid garment. Fulgrim (and anyone else making both their Religion and History checks) realize that the vestment must have belonged to a priest of Clangeddin Silverbeard, the lawful exarch of Moradin.
The rune "alaghor" is stitched in gold thread repeats along the two-inch hem of the vestment. "Alaghor" is dwarvish for "those who demonstrate valor in battle." Clangeddin's emblem is stitched into the V-neck facing of the tunic portion of the vestment; a pair of crossed silvered battleaxes forms an emblem that is embroidered repeatedly in miniature on the facing.
The panels themselves are a marvel. They tell the story of Luruar--commonly known as the Silver Marches--and the confederation of cities in the north of Faerun under the leadership of Alustriel Silverhand, the elven leader whose goal was to protect the North against a growing horde of orcs and giants.

The years 1368 through 1370 DR were particularly turbulent for the city states of northwest Faerûn. Troll attacks, orc hordes, an army of demons and barbarians, and an unusually harsh winter spurred the leaders of the northern cities to convene a council. Alustriel's diplomatic skill calmed many heated arguments between the human, dwarven, and elven council delegates. The political thrust of the council was to form an uneasy confederation in defense of the Silver Marches. The delegates appointed Alustriel leader.
Sometime between the winter and midsummer of 1371 DR, Alustriel declared that the confederation would be known as Luruar, in honour of the goddess Lurue. In so choosing, Alustriel rejected the suggestions of New Delzoun (in honour of the fallen dwarf kingdom) and Alustryr (in honour of herself), among others. Not long thereafter, Alustriel left the council, leaving her eldest son Methrammar Aerasumé to take over. Methrammar's ascension resulted in the immediate loss in support of Citadel Adbar, Citadel Felbarr and Mithral Hall (the dwarven stronghold).
The panels are filled with thread-of-gold images of dwarves battling stone giants in blazes of lightening, dwarves defending Citadel Adbar, the Glimmerwood, and other elven strongholds. One panel features what looks like Alustriel on a throne, a dwarf regent on her right.
The effect of the vestment's panelling is to glorify the involvement of Clangeddin Silverbeard and the Order of the Hammers of Moradin in the defense of Luruar, whilst simultaneously rendering the elves and humans a lesser honorific. The vestment is equal parts oral tradition and politics, a history of the dwarves writ plain and with pride. [/sblock]
