There are four subraces to the dwarves of Thame.  the Theron, Ieron, Delaron, and Meseron.  Each subrace has special abilities or immunities.  They also have particular dispositions (outlooks on life) which vary by their given race.  In short, each of the four races resembles a certain class that a normal character might play.  Therons are warriors, Ierons are priests, Delarons are wizards, and the Meserons are the nobility of the UDC who also hold property, businesses, judicial power, etc.
