General HTML Info Edit
HTML is a QUEST command used to open a web page in the in-game browser. It has one argument.
Argument 1 - Address Edit
The first and only argument of an HTML command specifies the address of the webpage to open. If it starts with http://, the game looks at that address on the internet. Otherwise, it will try to find the webpage within the world/html folder. Bear in mind that Well of Souls' in-game browser is based on a version of Internet Explorer, so all webpages intended for use within it should be tested with the in-game browser. Don't assume that just because they work in Chrome or Firefox, they'll work in Well of Souls - they might not.
