Quasqueton said:How big is your homebrew setting? (Can you describe it's size in relation to the Real World?)
There are four main continents and a "sub-continent" that are all attached to each other, much in the was that Eurasia was all connected at one point before continental drift gave us the continents that we have today. So, take Europe, Asia, African, and India and smash them all together and you've got the World of Samoth's "World Continent" (a misnomer, but, hey, what do they know?).

Quasqueton said:Is your setting a place to support multiple campaigns? Or do you change settings with each new campaign?
Absolutely - it is intended to support multiple campaigns. I've been working on it since December 1988 but only actually started using it as a real campaign setting in May 2001 with the 3E rules.
Currently, the group has only been exposed to two small areas: southern Esoria ("Spain") and northern Verundhi ("India"). There was travel along the way between the two, but the majority of the trip was made via magical teleportation so they didn't get to explore much.
Future campaigns will take place in different areas of the world and during different time periods.
