[Harry Potter] The Lonely Heights

A certain necromancer was crushed to death while dusting his beloved collectible skeleton. Well, at least losing his body wasn't much of a problem for a necromancer. As long as his soul remained, he could possess a corpse and return to life.

Unfortunately, this hapless necromancer's soul fell into a temporal rift and ended up in St. Mungo's in central London in 1981, reincarnated into the wrong body. Then he got involved in the story. The irresponsible necromancer set out to wreak havoc on the world.
