The Western House Rebellion
Accord of the Confluences
Most children are told to stay away from places where the forest grows thickest, for their wandering may take them through the thinning border to the Feywild. But the fey crossings were not always the only ones. These Confluences, or points where multiple Planes exist in the same space, wear thin the barriers into the World. Before a means of dealing with the Confluences was found, creatures from the Shadowfell came, along with those from the Astral Sea, Elemental Chaos, and the Abyss.
Once, horrors wandered freely, killing at will and spreading suffering of many kinds. The Thryn and Seten Manus found allies in the Genasi, who escaped the bondage of their elemental ancestors, and the Gnomes, whose life of service to greater fey was unbearable. Between these four peoples, a bond was formed, and a pact made.
The Accord of the Confluences was an eternal truce, a suspension of all aggressive activity between the peoples of the various Planes, for the duration of any time spent on Tjara, as well as travel through the points of Confluence. The Accord also created the Confluence Gates, planar devices of travel built on each point of Confluence, which allow an adept wizard to create a stable rift between the World and any of the Planes that participate in the Accord.
Not all Confluences have gates. The Minor Confluences, such as Fey Crossings and Astral Doors, have either been sealed or stabilized, and layers of protection have been placed upon them to discourage any foolish enough to try creating a new planar gate.
The last to have tried was Rak’sha Illan, a half-elf sorceress that lived not more than four hundred years ago. Her body was found in pieces, burned and still smoldering as it returned from the Nine Hells in the Astral Sea. The Accord does not apply to Minor Confluences, and the horrors of the Planes are patient, lying in wait for a chance to return.
