The Proclamation of Red Tears was issued by the Clan elders of the Followers of Set sometime between 1260 and 1277 CE. During this time Baybars, the first Mamluk king of Egypt, began a purge of non-Muslim supernaturals from his lands. After relentless attacks by Ashirra Cainites and the sacking of the main temple at Ombos by Muslims, fear gripped the Setite elders and they chose to decentralize the Clan. The Followers of Set carried away every scroll and artifact they could manage to the temples of other lands, temporarily abandoning their ancestral homeland. Many of these treasures never returned.
After these events, many methuselahs teeth-gnashingly accepted that they never would be able to expel foreign influences from their home. Others, including some of the Hierophants, chose to enter torpor, hidden away in their ancient tombs and wait until Set himself would lead the Clan again. Up to this day, Baybars is the most hated mortal in the history of the Clan.
