In my WIP Mortraxhian is a psychopathic killer who is mute because his tongue was cut out long ago as a punishment for his early crimes. This does not render him speechless however. Mortraxhian has the ability of mental telepathy and has acquired other magical abilities.
One of his deadliest skills is the ability to turn two dimensional. This grants him the ghostly ability to go through locked doors. As a two dimensional figure, he can slide through any available crack; like a door and its door jam.
To add more to his deadly countenance, he possesses an enchanted breast plate of armor that is made up of individual links in the shapes of feathers. He can multiply these links and have them take any form on his body. These links are sharp as a razor yet as sturdy as steel. With this ability to command each individual link, he can put it in the form of a sword, razor whip, or an array of throwing knifes.
Nothing pleases him more then to toy with his prey before cutting their throat. He always has had a fascination with using his sharp toys on living flesh. He is a dangerous menace that must be stopped.
