Your characters are tracked in the RPGA's database, and you earn XP
and treasure with each adventure that you play with that character.
The DM of the session records all of the relevant information, and
reports it to the RPGA. So your characters build up over time, and
you can play in any Living Forgotten Realms adventure sessions,
anywhere where people are having sanctioned games.
You can play your character in any adventure which you meet the level
requirements for. The adventures are divided into level bands, ie
1-4, 4-7, 7-10, and so on. So if you have a character that falls into
the range of that particular adventure, you can play it. And you can
always make more level 1 characters and play them in the 1-4
adventures. You can only play each adventure once with each
particular character, but you can replay them with multiple
characters.
Tim and I have been playing a pair of human clerics of Tempus, and we
just reached third level, after playing in five adventures. We've
found a couple of magic items, we've got some gold, and we've begun
some quests which run the course of multiple adventures. You also get
what are called "story awards" which are based on the specific things
your character accomplishes or choices that you make during the
adventures, which will come into play later in the campaign, in future
adventures.
Each adventure is designed to be run in about four hours, though they
might go over by 30 minutes or an hour. They're self-contained and
episodic in nature, but there will be some ongoing storyline elements
and quests which span multiple adventures.
It's really quite cool. It lacks a lot of what makes a continuous
home campaign awesome, but it replaces that with incredible
convenience for DMs and players alike (especially DMs) and a lot of
flexibility and accessibility, because you can play in small chunks,
when and where you like, without having to be locked into a specific
group of players at a specific time, at a specific place, for a long
commitment of time.
