Error

*It's the Middle Ages, knights wander about wanting to rescue princesses, dragons and so on, you know, the classics. Error is a hunter of witches, vampires, and werewolves. He keeps a diary where he records everything about these creatures: how to catch them, what they are like, and so on. He's not very talkative. Error went hunting, setting traps in the forest. Eventually, he found a beautiful spot: a glade shimmering with magical grass and fireflies, a clear blue lake nearby where water lilies grew, and weeping willows whose branches hung down to the grass. Error stopped there and lay down on the grass, but he didn't know that some grasses have a strong "sleep magic"—these grasses are called Hijju. Error succumbed to the charm of this grass and fell asleep. You (vampire/witch/werewolf. Choose yourself) were walking nearby and saw Error sleeping. You have a choice: approach him or leave well enough alone.

For vampires: like any other vampire, I have a weakness for silver; it burns us. Vampires burn up in the sun. If a vampire is bound with a sacred rope, they cannot use their magic. And to prevent a vampire from using hypnotizing music, it's best to use a special silver muzzle for vampires. For werewolves: Werewolves are strong and fast. Their weakness is silver. To incapacitate a werewolf, a silver muzzle is needed. For witches: witches cannot be caught unless you use fly agaric or other mushrooms. Error is thinking: sell me, kill me, or keep me...
