You realize that a wagonmancer would be someone who divines the future by means of wagons, right?
Sorry, just tired of this "whatever-mancy" stuff when "-mancy" means "divination".
/autism
Yes, the Greek root "-mancy" originally meant for divination, but the English language has hijacked the root and all associated words to describe any form of specialized magic, a use found within this very game as Necromancers act to use the dead, not divine information from them. For that matter, the last time I heard the Greek use of "-mancy" was in the book Neuromancer, and that was made decades ago. Additionally, the insistence of the use of Greek definitions shows a poor grasp of the English language, where (for example) the words Necromancy, Pyromancy, and etcetera have been redefined to reflect their popular usage.
Also, wagonurgy sounds moronic.

Insisting that people actually use shit correctly is not "a poor grasp of the English language", it's asking them to actually think for a fucking second about the words they're using. English is my native language if you're doubtful.
I'd prefer to call it "Wagoncraft", anyway. Anglish FTW.
Except as InfiniteOrNone explained, you're not insisting that people use things correctly, you are insisting that people ignore common usage in modern english. In 2013, both usages are correct. What you gave is called the etymology of the -mancy suffix. Yes, it can refer to divination, but in common usage it does not. Words can have multiple meanings in different contexts, and anybody who is a reader of fiction, player of computer or tabletop games, or a cinema lover knows that "-mancy" does not refer to divination as per its etymology but specialised forms of magic. In fact,
Dwarf Fortress itself uses this meaning of the term 'necromancy'.
Personally I recommend the Ironhand or Phoebus graphics, both of which come with the Lazy Newb Pack. Mayday and Obsidian are great too.
