Remnant Church of Treesian Unorthodoxy

The Remnant Church of Treesian Unorthodoxy (internally known as the Bishopric of Eliria within the Treesian Unorthodox Church, also also known as the Treesian Unorthodox Church for short) was the last remaining bishopric of the Treesian Unorthodox Church. It was dissolved upon the conclusion of the year 1692. It was a small denomination, with only some 5,000 members across Elwynn and Arboria.

Sided with the motherchurch in Treesia during the Schism of 1490 (the other side becoming the Church of Elwynn). Internally, it called itself the Bishopric of Eliria, however, the Church of Elwynn cathedral and diocese claimed this name, and therefore the Church was officially registered by the government of the Barony of Elwynn as the "Remnant Church of Treesian Unorthodoxy".

On 8.XI.1691 AN the prelates of the Remnant Church of Treesian Unorthodoxy were invited by the Princess of Elwynn to attend upon her at court in Eliria. The delegation, that duly arrived on the 11^th, was hosted by Jael Jemima Truls, the Commissioner for Coordination, who subjected them to wine and hospitality for most of the day whilst pressing them politely for answers on certain matters pertaining to church governance. The evening audience with Kamilla Winther finally took place in the reception hall of Eliria Castle, where those present could not help by notice that she addressed them from an ornately carved curule chair set upon a raised marble dais. To their considerable surprise they found themselves discussing at length the "verdict of history that is manifest in the supplanting of Treesia by Craitland and the ascendance of the Riqi Elluenuuerssuarion". The discussion, which had become thoroughly disagreeable for the fatigued and drink befuddled delegates by the end of the audience, concluded with the presentation of a writ, on vellum parchment edged in silver and white gold gilt, instructing the Bishopric of Eliria within the Treesian Unorthodox Church to consider its historical mission to be fulfilled and to give "serious and timely consideration to the merits of returning to the mother church in full communion", by which was understood to mean to prepare for absorption into the enu arsaqarion Elirion.

After lengthy discussions and negotiations between the Church of Elwynn and the Remnant Church, an end to the schism was agreed in the final days of the year 1692, with New Year's Day 1693 becoming the day of communion (Communion of 1693), thus ending the two-hundred-and-two-year long Schism of 1490. Because most of the differences between the churches were agreed to be schismatic and not heretical, the negotiations revolved very little around theological matters, and merely canonically legal and administrative matters. Among other things it was agreed that:

• The Bishop of Eliria would retire with full honours as a former sagart of the Church of Elwynn
• The ordinances of the Remnant Church would remain fully valid
• Mass could be celebrated in the Treesian rite as an alternative, a more conservative form of the Church of Elwynn rite previously celebrated by the Remnant Church and done in the Treesian language rather than the vernacular one, and the decision of which rite (the Elwynnist, the Arborianist or the Treesianist would be chosen by the local congregational synod)
• Any mutual excommunications to be revoked ex post facto
• The Church to remain a spiritual realm and not be involved with the political, carnal and secular disputes of the world.
