Red Cap

The Red Cap is a sub-species of Gobline that normally inhabit ruined castles.

In Folkelore
In Border Folklore, a Red Cap is a type of malevolent murderous dwarf, goblin, elf or fairy.They are said to inhabit ruined castles found along the border between England and Scotland. Redcaps are said to murder travellers who stray into their homes and dye their hats with their victims' blood (from which they get their name). Redcaps must kill regularly, for if the blood staining their hats dries out, they die. Redcaps are very fast in spite of the heavy iron pikes they wield and the iron-shod boots they wear. Outrunning a redcap is supposedly impossible. (From Wikipedia)

In MGE
Red Caps are distant cousins to the Goblin and Hobgoblin but they have a more mature appearance unlike the younger look of their cousins. These goblins tend to stay by themselves and are rarely seen in large groups, the largest group spotted only consisted of two Red Caps playing their version of tag, using their pole-arm weapons. Red Caps themselves, when not looking for a mate, are rather childish, playing games with random travelers, one after the other. Once the traveler is exhausted, they knock them out and use their pikes or spears to draw blood, which they dip their cap in. They do this so they can maintain their life for longer periods of time. When they find a man (or woman) that interests them, their approach is very similar however, once they knock their prey out, they decide to forcefully dominate him, marking him as hers and hers alone, becoming a yandere.The Red Caps also become extremely clingy to her mate, not venturing far from him or her. If she sees her lover even talking to another, she will torture the other woman and dip their cap in the spilled blood.Should a Red Cap drink the blood of their victim instead of using it to stain their cap, they will become drunk as if they drank too much alcohol.
