Goblin

"Goblins are the most mischievous of creatures. Mischievous and dangerous [...] Goblins will stop at nothing to get their hands on the one thing they value above all others, gold."

- Gaius A Goblin is a type of mischievous, humanoid creature with green skin, black tattoos, and an insatiable lust for gold.

History
When a woman took bella-donna, which could induce hallucinations, she experienced a hallucination of a Goblin dancing in the fiery coals. The Witchfinder, Aredian, used this as evidence that a sorcerer was loose in Camelot (The Witchfinder).

Merlin once accidentally let a goblin loose in the city of Camelot whilst was fetching an old tome for Gaius. After being released, the goblin inhabited the body of Gaius and began to wreak havoc on the kingdom. After King Uther lost his hair and Prince Arthur grew a pair of donkey-like ears, the citizens of Camelot knew that something wasn't right. The goblin then put the blame on Merlin after hiding a book of spells in his room. Determined to see justice, Gwen and Merlin tricked the goblin into licking a gold coin laced with poison. The tiny creature fled its dying host and was trapped inside the lead box once more. Later the box was stored deep into Camelot's vaults, where no one could release it again (Goblin's Gold).

Characteristics
Goblins enjoy playing tricks and pranks on innocent people. They are magical creatures capable of transforming themselves into small bright balls of light. Whilst in this form, they are capable of possessing another living thing and controlling their body and thoughts. Goblins are also capable of magic and can perform various magical spells without an incantation. They also have psychic abilities and can look into the heart of a person and read their mind. While in the body of a Human, they are exceptionally strong, as the elderly Gaius was able to defeat a muscular man in arm wrestling.



Biology
Goblins are small creatures, at about four feet tall. They have lime green skin and long, pointed ears. They have large amber eyes and are capable of human speech and intellect. Goblins have some kind of black tatoos or markings all over their bodies. Once in the body of another, goblins are notoriously difficult to remove. The only known way is to poison the person, as if the goblin's host dies, the goblin dies with them. Once the goblin has left its host, the person can then be given the antidote to the poison. Another of the goblin's weaknesses is that once incased in a box bound by lead it cannot escape. Goblins are famous for their constant thirst for gold and will not allow anyone or anything to get in the way.
