Kinda have to add that we do know a lot about Ed's campaign since his players have discussed it at Candlekeep quite often. And he does use his NPCs quite liberally (Storm more than El from what I gather).
Well, I'd hardly say "a lot"; Lady Hooded One has indeed described Ed's campaigns occasionally, but not that often. And yet (to my knowledge) she's the only player who has done so publicly. In all my years on that forum I've seen only a handful of longer descriptions featuring gameplay and plots -- it's more or less short comments (added into Ed's replies) like "We Knights have met this NPC twice, and one of these times took place at a masquerade and another time we glimpsed him flying over the rooftops of Suzail at a distance" (to give a crude example).
