The Alchemist's Guild

 
OMNIS QVI CORVSCAT EST OR -- All That Glitters Is Gold 

For four hundred years the alchemists have been searching for a way to turn lead into gold, although all they have succeeded in doing is turning gold into less gold. Their experiments frequently explode and the guild house has been rebuilt many times... 
 

The Alchemist's Guild is opposite the Gambler's Guild. Usually. Sometimes it's above it, or below it, or falling in bits around it.
     -- (Terry Pratchett, Men At Arms)

More resent experiments produced an ivory substitute which resulted in a eventful if deadly game of pool, and a method of producing moving pictures which not only had a tendency to explode but also cause a tear in the fabric of reality.
 

The Assassin's Guild

 
NIL MORTIFII SINE LVCRE -- No Killing Without Pay 

All assassins had a full-length mirror in their rooms, because it would be a terrible insult to anyone to kill them when you were badly dressed. 

     -- (Terry Pratchett, Pyramids)
