Mulciber I

"...-Nott, Rosier, Mulciber, Dolohov- waiting for your return... What devoted friends, travelling so far away in the snow and the night just to wish you good luck in trying to get a teacher position!"

- Albus Dumbledore to Tom Riddle.

Mulciber was a wizard, a Slytherin student at Hogwarts School of Witchcraft and Wizardry and one of the earliest Death Eaters of Lord Voldemort. He was possibly the father of Mulciber. He fought in the First Wizarding War, and travelled to Hogsmeade in order to "wish good luck" to Tom Riddle in trying to get a teacher position at Hogwarts. It is possible that Mulciber was deceased before the start of the Second Wizarding War, but, if he did not, he possibly fought at the Battle of Hogwarts and was presumably killed or imprisoned in Azkaban after Voldemort's final defeat.

Early life
Mulciber might have attended Hogwarts School of Witchcraft and Wizardry at the same time as Tom Riddle, and he may have been a member of Slytherin house, as well as a member of Tom's gang and the Slug Club. After Hogwarts, Mulciber became a Death Eater.

First Wizarding War
Mulciber fought in the First Wizarding War, along with many other Death Eaters. He was also one of the Death Eaters who travelled to Hogsmeade to "say good luck" to Voldemort, during his attempt to ask for work at Hogwarts, along with fellow Death Eaters Nott, Rosier and Antonin Dolohov. He was the father of the Mulciber who attended Hogwarts with Severus Snape in the 1970s. After Voldemort's first downfall, Mulciber was killed.

Second Wizarding War
Mulciber was killed during the First Wizarding War; His son participated in many battles during the Second Wizarding War, including the Battle of Hogwarts. He (Mulciber Jr.) was proably killed during that battle.

Post-war
After Voldemort's final defeat, Mulciber's son was proably killed during the Battle of Hogwarts.

Etymology
May refer to Mulciber (Hephaestus), meaning "smelter", is an alternate name for the gentle son of Zeus and Hera who had a club foot and was a craftsman and blacksmith in Greek mythology. In Roman mythology he is the god of fire and metallurgy, Vulcan. More likely Rowling n refers to Mulciber, a character in John Milton's Paradise Lost, a story based on mankind falling into sin and the struggle of heaven and hell. Mulciber was a fallen angel who is the architect of Pandemonium, the capital of Hell and home to the demons' council.

Behind the scenes

 * During his trial, Igor Karkaroff accused a Mulciber of being a Death Eater. It is not known whether he was referring to the older or younger Mulciber.
 * It is possible that Mulciber may have been one of the unidentified boys seen with Tom Riddle in Horace Slughorn's memory, although this has not been confirmed.
