Sinsar Dubh1: a Dark Hallow2 belonging to the mythological race of the Tuatha Dé Danaan. Written in a language known only to the most ancient of their kind, it is said to hold the deadliest of all magic within its encrypted pages. Brought to Ireland by the Tuatha Dé during the invasions written of in the pseudohistory Leabhar Gabhala3, it was stolen along with the other Dark Hallows and rumored to have found its way into the world of Man.
I blinked. Then I scanned down the page for the footnotes.
Among certain nouveau-riche collectors, there has been a recent surge of interest in mythological relics, and some claim to have actually beheld a photocopy of a page or two of this "cursed tome." The Sinsar Dubh is no more real than the mythical being said to have authored it over a million years ago—the "Dark King" of the Tuatha Dé Danaan. Allegedly scribed in unbreakable code, in a dead language, this author is curious to know how any collector proposes to have identified any part of it.
The Tuatha Dé Danaan were said to possess eight ancient relics of immense power: four Light and four Dark. The Light Hallows were the stone, the spear, the sword, and the cauldron. The Dark were the mirror, the box, the amulet, and the book (Sinsar Dubh).
Leabhar Gabhala (The Book of Invasions) places the Tuatha Dé Danaan thirty-seven years after the Fir Bolg (who followed Cesair, the granddaughter of Noah, the Partholonians and the Nemedians) and two hundred and ninety-seven years before the Milesians or Q-Celtic Goidelic people. However, earlier and later sources contradict both the true nature of the Tuatha Dé and their date of arrival as put forth by this 12th-century text.
