Have posted this before but will also add it here. So far I've only had time to get about 2% of the info that I've got and want to make available through the site up, but there is still more than a hundred pages of info on the World of Ærnth/Channel Cities wiki:
http://www.channelcities.com/wiki/index.php/Main_PageIt is the start of a wiki (started it several years ago) that I hope one day will be useful to many gamers. All of the fantasy based material that I've written for the GuildCompanion.com e-zine and for Guild Companion Publishing so far has been based within this setting. It started out as an alternative to a couple of city settings intended for thieves and other subterfuge/intruige types (the Channel Cities portion, which is the most populated and the economic center of the World of Ærnth) that I had purchased back in the early 1980's but was very disappointed with. Then other parts of the world grew out of other small kingdoms (Archendurn Kingdom and other places) and wilderness areas (remains of the Ruglund Empire and other areas) that I designed/ developed/ detailed for other games that I ran in the early and mid-1980's.
Thus I started to pull all of these locations together into a single world-setting so that all of these different locations and histories would be consistent and would all tie in together (as an example, the city of Argentum (the island city in the middle of the channel of the five Channel Cities) started out as a remote trade stronghold as part of the Ruglund Empire that was established only a couple of centuries before the start of the fall of the Ruglund Empire. The people of the Archendurn Kingom were also some of the earliest people to rise up and rebel against the nearly globe-spanning Ruglund Empire. The same empire that became so large and powerful that despite it being able to maintain its hold over dozens of different rebellions around the world finally fell to the internal corruption that had been eating away at the roots and central power structure of the worlds greatest empire for many centuries. It was that corruption and the evil and chaos that was its fertilizer that allowed the rebels to finally bring the empire down. After one and a half millenia, the worlds greatest empire fell and in the following millennium one of its remote trade ports and its surrounding communities grew into the new economic and power center of the world.
