The Stone is a black block residing near Stregoicavar Hungary. It has been the altar of a cult that lived there and may be part of an ancient city in that area.
A similar stone has been found in the Yucatan, though the two are not identical.
The Stone appears as a hexagonal block about sixteen feet high and about a foot and a half thick. It is of some shiny black stone and is covered with as yet untranslated hieroglyphs.
The Stone is said to cause constant nightmares in anyone who has slept near it. At Midsummer Night a ghostly ceremony is carried out by the long dead inhabitants of the valley and the toad god they worshiped.
The Stone's origins are long lost, though some visitors have theorized that it could be the base of some immense pillar or the pinnacle of an ancient and buried city named Xuthltan.
The Toad Cult
In recent history the Stone was used as an alter by the inhabitants of Stregoicavar. These people stole young girls and infants from other villages to the south and sacrificed them on the altar in a gory ritual. These cultists worshiped some sort of toad god, possibly Tsathoggua.
The ritual consists of an elaborate dance between a naked priestess and a wolf headed priest who chases and whips the priestess. At the pinnacle of the ritual the priestess, whipped to death crawls to the Stone while the priest dashes an infant against it. Then the toad god appears atop the altar and a sacrificial young girl is fed to it.
This worship was stopped when Turkish invaders wiped out the villagers and killed the toad god. The Turkish scribe Selim Bahadur recorded the event and placed it in a lacqured case which also housed a small idol of the toad god. The case was later buried with the Count Boris Vladinoff. The Count was killed where he stood in shock after reading the Turkish manuscript and was buried by his collapsing castle. The case was later uncovered by an unnamed author in the nineteen-hundreds and was then tossed into the Danube.
The Stone has been written about several times.
It is also described in Otto Dostmann's Remnants of Lost Empires. (Berlin, 1809, "Der Drachenhaus" Press) There Dostmann describes it as being left by the Mongols and no older than Greco-Roman ruins. It does however mention the village Stregoicavar.
Another mention appears in Dornly's Magyar Folklore under the chapter on Dream Myths. There it describes the Midsummer Night visions and the nightmares of those who have slept under it.
