Most people have trouble with lycatherope and demodand. Most of what u said was correct, but dullahan is not a headless horseman. Keep guessing, thats probably hardest one.
Lycatherope is in general a shapeshifter, not necessarily a werewolf.
A demodand is another name for demon. If u dont know what that is, i pity u.
Kraken is a legendary giant squid, or in some mythologies octopus, though in very few.
Wyvern does NOT have fur, its a dragon that can't breathe fire, has no front claws, and wings build so they can hover.
The term succumbus simply describes a type of female demon, though certain mythologies that they can enter dreams.
Sorry beezle, except for jormungand u got me
And castlevania is where i got some of the names, but not where i got the definitions (or warcraft 3) (or 2 or 1)
Lich is simply an undead mage, considered nearly invincible, but there are certain things one can do to destroy them.
