The "Of-Henge Yuirs"
Beginning humbly assisting Phandalin with regional challenges, this group became empowered through the Forge of Spells just before it was buried in the destruction of the Wave Echo Caves. Their heroic adventures continue.
Among the group are members of the Lords Alliance, Order of the Gauntlet, Zhentarim, Harpers, and the Emerald Enclave, the last two of which were present at the stone henge-like circle of menhir of the Yuir, when an ancient godling granted them their marks to employ the circles for traveling. This naming the group (to some) the "of-henge Yuirs".
