31 Days of Monsters: The Lidérc

If you take the egg of an all-black chicken and incubate it in a pile of manure, it will hatch into a lidérc. A Hungarian shapeshifting demon that attracts money to its "owner", a lidérc can also transform itself into a fantasy lover for its master much like an incubus or succubus. If kept too long however, a lidérc will begin to drain the life from its owner, delivering the victim's soul to it's real master, the Devil. The best way to rid yourself of a lidérc is to give it an impossible task to complete. If unable to finish the task, it will either return to Hell or tear itself apart in frustration.

31 Days of Monsters: Basilisk

The basilisk was said to be the king of serpents because of a crown-like crest on its head. Basilisks are born when a chicken hatches an egg from a snake. One look from a basilisk is said to be able to kill an average man, and if stabbed, their blood can flow up swords to poison their slayers. They are aggressive to all living things, and when they cannot find animals to attack, they preoccupy themselves withering plants with their breath. Weasels and mongooses are said to be the only animal that is immune to their stare, but one of the easiest and surest ways to kill a basilisk is with a rooster. If a basilisk hears a rooster crow, it will drop dead instantly, no muss, no fuss.
