While questing for a dynamic version of the Eberron character sheet for an upcoming PBEM campaign I'm playing in, I came across this nifty Eberron World and Planar Calendar Utility posted as a Web enchancement by Wizards of the Coast.

It's a utility -- available in online and offline editions -- that helps you keep track of Eberron's many moons, as well as its planes. One of the aspects of Eberron that I really enjoyed was its unique plane set-up -- basically, the "closer" a plane is to Eberron, the more magical effects it has on the world. The further way it is, the lesser the effects are, and the harder it is to reach the plane and to summon beings from it.

Of course, keeping track of all those satelllites could be a real headache for detail-loving Dungeon Masters (like me, although I'm not running the campaign) so this utility is a welcome addition to the DM toolset.

As for the dynamic Eberron character sheet -- one that I can update on my computer -- I never found one, but I did find this nifty four-page character sheet.
