The first fortifications of Gwyncærn were believed to be built by the Aðulæ sometime shortly after the First Apostasy around the year 25 A.C. It is rumored that construction originally took place on the burial mound of a great Aðulæ sorcerer some twenty to fifty years before the Long Dark, though no evidence of this has been found to support this theory. Construction began with silverpine and sea-sap mortar and stood until 59 A.C when it burnt down.

It was rebuilt in the year 60 A.C using much of the same materials as before, though the building was reinforced with protostone supports. The second incarnation stood for an unknown sum of time before eventually burning down again during the Great Migration in 833. Though much of the wood was reduced to ash, the stone supports survived the flame and were repaired and built upon. Construction of the still standing building began in 836 and was finished in 839.

During the Scourge of the Abbot in the year 841 A.C, Gwyncærn was converted from a temple of worship to temple of healing for the sick. Under the command of Thaumaturge Eradredd II, who housed an ever growing resentment towards foreigners ever since the fire of 833, treatment and housing was offered to sick outsiders. Instead of keeping his word, Eradredd took men, women, and children alike down to a series of tunnels under Gwyncaern and locked them in the dark to starve to death. A mass grave containing only the bones of children was accidentally discovered in 1181 during excavation. It is passing strange that no adult corpses were found and some even whisper that there were some who survived Eradredd’s terrible labyrinth, though none tell how. They say that they were altered from their years in the dark, terrifying, strange to behold, and neither beast nor man.

Though Gwyncærn received a dark reputation early on, after the death of Thaumaturge Eradredd in 877 A.C, many of his predecessors worked hard to regain the trust of the people.From the Early Middle Ævum to the Great Age of Chivalry, Gwyncærn has gained a reputation as a place of great learning, historical significance, and beauty. Gwyncærn is composed of four main levels. The first level houses the Grand Archive, the largest collection of historical texts in the world, and is surrounded by two reflection towers on either side. A magnificent winding staircase ascends to the Archodeon Chantry on the second floor and then to the Veiled Dormitories which house the curators of the temple. Lastly and highest up is Theobald’s Belfry, named after Emeritus Theobald (depicted with his enchanted harp below his personal coat of arms), Patron Scholari of Gwyncærn. It is rumored that the sonorous Carillions of the Belfry were cast from the holy bronze armour of fallen Aðulæ.
