Preiwan is a low level member of the Tyrants (a criminal organization in Sharn), and a typical quick replacement when one is needed to do a particular job. Even with a low Charisma, Preiwan has a +14 disguise bonus when he's had a chance to see whom he is replacing combined with his shape changing.

PCs are most likely to encounter replacements like Preiwan when dealing with the Tyrants, especially if they are dealing with front organizations. A quick change of "languages known" can make for other replacements skilled at replacing elves or other races than dwarves.
