M is for... Maldovar, Dorium

Dorium Maldovar was a large blue-skinned humanoid - a native of Crespallion - who ran a successful trading post which he named the Maldovarium. A black marketeer, he could obtain any item for a price. River Song approached him to purchase a Vortex Manipulator. Dorium obtained one by killing its Time Agent owner. To avoid paying, River spiked Dorium's drink with microscopic explosives, the remedy for which which she then swapped for the Manipulator.

He had established relations with the infamous Headless Monks, and was approached by Madam Kovarian and Colonel Manton of the Church of the Papal Mainframe to get information about them - as they sought to forge an alliance against the Doctor. Fearing he would be dragged into the conflict, Dorium shut down his trading post and was on the point of fleeing when he was stopped by the Doctor - come to call in an old favour. He wanted Dorium to help find the kidnapped Amy Pond and her child.

Dorium accompanied the Doctor to the asteroid Demons Run, where the Headless Monks and the Kovarian forces had gathered. 

Dorium attempted to negotiate with the Monks, thinking they would treat him as a friend, but they decapitated him.

His still living head was deposited in an ornate box in the Seventh Transept, a subterranean complex where the Monks stored their heads. The Doctor was taken there by a man named Gantok. Dorium passed the time with a computer chip in his brain. He was able to tell the Doctor about the legends of his fate: to perish on the Fields of Trenzalore when the final question was asked - a question that should never be answered. The Doctor took Dorium's head with him in the TARDIS whilst he investigated ways of escaping his fated demise at Lake Silencio. After achieving this, he had Dorium's head returned to the Seventh Transept. Dorium asked him the question: "Doctor who?"...
