The priests of the Silver Flame have always sought to spread their faith, and when word reached Thrane of the new city taking shape across the Thunder Sea, the cardinals were quick to send ministers and templars to the shattered land. A wave of Thrane immigrants helped establish the keep now found in the Temple district. Keeper Tzandra had a vision of a ministry that would bring the Flame to the drow and the giants and a bastion that would hold back any darkness that might threaten the city.
Reality fell far short of the dream. Stormreach was founded by pirates and smugglers, and the priests of the Silver Flame received a cold welcome. Missionaries sent to spread the word to the dark elves rarely returned, and by the time King Thalin of Thrane died, only a single minister and a handful of acolytes were left at the keep. This proved to be another turning point for the Silver Flame in Stormreach. After long debate, they rejected the Keeper’s decision to assume control of Thrane. Both church and crown had roles to play, the priests explained, and it was a mistake for one to supplant the other; it would only lead the church away from its true purpose.
The Council of Cardinals was infuriated by this rebellion, but with the Last War in full swing, the Thranes couldn’t afford to send new forces to this distant post. Instead, the city was formally severed from Flamekeep. To this day, the keep receives no support from Thrane, and the faithful are warned to beware the words of these heretic priests. Now that the war is over, some believe that Flamekeep should reclaim the keep. However, the people of Embers stand behind their minister, and Keeper Jaela Daran is more willing to accept diversity than her predecessors had been; for the moment, Stormreach has been left on its own.
As a result, the Silver Flame has little power in Stormreach. Three priests serve at the keep: Minister Jirian Zayne (NG male half-elf adept 4/expert 3), Acolyte Myla Flamesworn (NG female human adept 1/expert 4), and Templar Guin Silverblood (LG male human expert 3/warrior 3), a master archer who trains members of the congregation in the use of the longbow. The keep is a sanctuary for the faithful of the Flame, and the priests of the temple are glad to work with traveling paladins or clerics. But they learned long ago that they lack the strength to fight the darkness within or below Stormreach, and they save their spells to protect those in true need of sanctuary.
Opposition to the theocracy is only one of the heretical beliefs found in Stormreach. A number of the people who helped establish Embers came to pursue their unconventional traditions without fear of persecution. Others have adapted their faith over the course of generations in Stormreach and exposure to legends of the past.
He only speaks of it to his most trusted parishioners, but Guin Silverblood practices the traditions of an ancient serpent cult, passed down to Guin’s father by a feathered yuan-ti. Although the values are similar to those of the modern church, this faith teaches that the Silver Flame was kindled by the sacrifice of the couatls in the dawn times; Tira Miron and the Keeper of the Flame are stewards who bring the light of the Flame to humans too limited to see the ancient force on their own. Guin has served as an intermediary for the shulassakar yuan-ti in the past, and this could serve as the basis for an adventure.
