Demolitionist

The Demolitionist is an NPC vendor that will spawn once the following criteria have been met:
 * There is an empty house.
 * You have an explosive in your inventory.
 * Merchant is alive.

If the Demolitionist is killed, he will only respawn if the above conditions are met again. This means you must place an explosive in your inventory. Having them stored in Chests will not fulfill this requirement.

Items sold
Once the Demolitionist has moved into a house, he will sell the following:

Note: As with all NPCs, right-clicking an item will allow multiple purchases rather than purchasing it one by one.

Names
The demolitionist may have any of the following names:


 * Bazdin
 * Beldin
 * Boften
 * Darur
 * Dias
 * Dolbere
 * Dolgen
 * Dolgrim
 * Durim
 * Duerthen


 * Fikod
 * Garval
 * Gimli
 * Gimut
 * Jarut
 * Morthal
 * Norkas
 * Norsun
 * Ovbere
 * Oten


 * Tordak
 * Urist

Some of these names are references to dwarf characters, such as Gimli from The Lord of the Rings, Beldin from "The Belgariad", or Fikod and Urist (generic everydwarf names) from Dwarf Fortress. Durim is very close to Durin, a dwarven king mentioned in J.R.R. Tolkien's books, and in "The Hobbit: An Unexpected Journey". Morthal is a name of a Hold Capital in "the Elder Scrolls V: Skyrim."

Trivia

 * The Demolitionist's appearance seems to be based on dwarves from many games, films and works of literature. He is significantly shorter than other NPCs and has a beard. Furthermore, his mining helmet, lantern, and the fact that he sells Explosives fits the trope of dwarves preferring underground environments.
