Editing Eberron (section)

==Thirteen Minus One==
An unusually high percentage of Eberron revolves around having thirteen of something, with one of them lost or destroyed (Read: a Baker's dozen). There were thirteen moons/alternate planes, but one had its connection severed. There were thirteen marks, but one was wiped out. There are thirteen regions in the modern Khorvaire, but one is the Mournland. There's thirteen holidays, but people ignore one (work-a-holics the lot of them). There's even thirteen kinds of halfling tea (called "tal"), and the knowledge of making one of them was lost in the Xoriat incursion.

(for DDO players who did the Shroud, THIRTEENTH ECLIPSE ANYONE!!!???? ''Duhh, thats exactly the reason for the imbalance that caused the invasion'')

Baker himself has stated that they'd just independently set two things in groups of 13-1 and thought it would be cool to run with it. Keith Baker didn't even notice the obvious "Baker's dozen" pun until someone pointed it out to him.
