The villa was built in −2482 DR by the Netherese Orogoth family. It served as their headquarters for their dark magical experiments and efforts to gain control over dragons and to assume dragon shape. The villa was the site of the family's creation of the ophidians, as well as of a titanic civil war in −2211 DR during which the family seemingly wiped itself out.
In the Year of the Moor Birds, 90 DR, yuan-ti from Ss'thar'tiss'ssun raided the ruins and accidentally awoke a powerful black dragon known as "the Old One". Despite repeated incursions by the yuan-ti, the ruin henceforth became the home and lair of this Old One and his descendants, who claimed to be the last scions of the ancient Orogoth family.
By the Year of Fallen Guards, 111 DR, the Old One had enslaved several tribes of ophidians and had recruited Netherese wizards fleeing the fall of Anauria, and the descendants of these groups would also come to populate the ruined villa. Following another civil war within the family in the Year of the Dracorage, 1018 DR, the Old One become a dracolich in the Year of the Immortals, 1037 DR with the help of the Cult of the Dragon. The family then expelled the Cult, earning themselves another longstanding enemy.
In the mid-to-late 14th century DR, the reputation and mystique of Orogoth suddenly exploded. The ruin of became well-known among treasure seekers throughout the Sword Coast, with Amnian adventurers and merchants becoming particularly enamored with tales of hidden caches of gems collected by the powerful ancient family. This fame was such that the ruin was mentioned in every guide to the area, and even children heard tales of it. However, those who visited were killed, sent fleeing, or were transformed into beasts.
In the mid-to-late 14th century DR, the villa was home to the black dracolich Calathanorgoth—better known as The Old One—and his living great-grandson, Wastirek, along with Wastirek's mate Vilholin and their children, Awsidorg, Woklef, Cheleen, and Kasidikal. Additionally, it was home to a growing number of half-dragons who traced their ancestry to Calathanorgoth, thus calling themselves the Scions of the Old One.
Non-dragon inhabitants included human wizards descended from the Netherese recruited by Calathanorgoth centuries prior, many of whom studied ancient magic and collaborated with Halruaas wizards. In addition, the villa was the headquarters of the largest ophidian tribe in the High Moor, appropriately calling themselves the Tribe of the Old One. Owing to experiments with ophidian eggs, House Orogoth created a means to manufacture half-dragon versions of the creatures. As of the 1370s DR, the Tribe of the Old One was led by a half-black dragon ophidian named Abreauth.
