Schism War

Perhaps the single defining event in the history of the Order of Hermes since its foundation, the Schism War wiped House Diedne from the Order and had substantial ramifications for many of the Order's institutions and organizations.

The Schism War happened in early eleventh century, after the crisis of House Tremere in the ninth century, which resulted in the Sundering, and the Corruption of House Tytalus in the 10th century. It caused the cancellation of many of the Regional Tribunals of 1004 and reached a point of no return when House Tremere declared war on House Diedne in 1010, soon to be followed by Houses Flambeau and Jerbiton.

Magi Trianomae of House Bonisagus then convinced the Primus of House Guernicus to call for an emergency Grand Tribunal of resolution instead of the Regular Tribunal that would otherwise happen in 1011. The Primi of Houses Bonisagus and Mercere quickly agreed, and the Grand Tribunal eventually decided to renounce House Diedne entirely.

The Schism War was terribly divisible and remains a haunting memory to this day.

The Houses and the Schism War

• House Diedne was by all appearances destroyed as a direct result of the Schism War, after being under suspicion of diabolism and human sacrifice.
• House Tremere was the main accuser, albeit unofficially and by way of the Wizard Wars between its members and those of House Diedne, until it finally decreed war against House Diedne in 1010. When the Grand Tribunal of 1011 was called, the Primi of Houses Diedne and Tremere were the only one not called to participate (although they were still represented by their respective Quaesitors).
• House Tytalus was headed at the time by fifth Prima Kalliste, who was widely mistrusted in her own House and perceived to be following the lead of House Guernicus meekly. Before the Schism War was fully resolved, Kalliste was murdered by a filius of her successor, Klynoites the sixth Prima.
• House Guernicus, headed by Primus Antonius, attempted a peaceful solution and ended up assaulting House Diedne among terrible internal conflict.
• House Ex Miscellanea was headed by Primus Basilicus, who was to participate in the fateful Grand Tribunal of 1011 carrying a considerable number of proxy sigils that might have turned the tide of decision. Unfortunately, he did never arrived, at least in able time.
• House Flambeau, headed by Primus Entisimon, generally approved of the War and enabled it by having many among its ranks decree Wizard Wars against members of House Diedne. Eventually Entisimon rallied the whole House against House Diedne at a famous speech at Val-Negra.
• House Jerbiton largely kept apart, choosing instead to help in the period of reconstruction.
• House Bonisagus was terribly divided by the conflict, widening the rift between the Trianoma and Bonisagus factions, and leading to the abdication of Primus Thamus Collis after the renunciation of House Diedne.
• House Mercere was already well-established in its role of running communications within the Order of Hermes, and was instrumental in the calling of the Grand Tribunal of 1011.
