lets say some heroes defeated the cult of the dragon and stopped Tiamat from coming back to Faerun. But now they have the 5 dragon masks. Would the council of waterdeep let the heroes who saved the realm really keep them all in one group? Or try to acquire them? If it becomes widely known that the PCs have all 5 dragon masks, they will become "the hunted" overnight; many, many factions, power groups, rival adventuring bands, thieving guilds and cabals, and the "secret agents" of many petty rulers will all be trying to get the masks!
