Lissandro was a world of the Imperium.

In 383.M41, the Warp Storm Iagon visited its fury upon the world, causing the ruling body of the planet, the Quarrum Immaculate, to scour their ancient libraries for an answer. They eventually discovered an ancient and mysterious hexagrammatic symbol that legend said could ward off the powers of the Warp. Within a month, all registered citizens had the symbol implanted upon them.
When the Inquisition later reached the planet with a fleet of Black Ships, the citizens with the implants began to convulse and Pink Horrors rose from their corpses. By sunset, the cities of Lissandro were overrun. The Inquisitors, under siege at the Quarrum's palace, requested the aid of the Grey Knights. However by the time they arrived, every city on the planet had been devoured. The Grey Knights took the battle to those Daemons still remaining, and when they entered the ancient libraries that were the original source of information for the hexagrammic symbol, they found the Blue Scribes waiting. The Scribes vanished into the Warp and it becomes clear that the symbol left in the library was not one of banishment, but invitation.
