multiplayer characters you can bring into games instead of having to play their character companion.
The problem with importing characters into someone else's game is you can bring in items from later quests and it might have adverse effects on the main module's progression.
I personally would not be happy if someone came into my module with 3 bloodstone shards, and messed up my end of time progress, or they had a quest item that closed out a quest line that I hadn't even looked at yet.
