Here's an Idea from an old Gary Gygax (you know if you know) Fan from The AD&D days.... (was a DM so i got a ton of these)
So All these Higher Ups go to Camelot and Camp; to find the Big Dragon in the PvP castle; and Kill em for Mad XP and the Treasure Hoard.
See, mostly Dragons View Humans as minor Annoyances like Flys. In my world of RPing this would be quite different. Sure the Players would all run to kill the dragon and get the XP and Treasure; but what then....
So one day after one of these Dragon Hunts; the Entire Area Surrounding the Castle including Avalon and Camelot is attacked by 5 or so Dragons. Literally everyone (yes the players) and Everything including any innocent MOBs are attacked by these Dragons who Proceed to Lay Waste to the Entire Area (thus sending most Running in a Panic)...
Of Course the Biggies are gonna hear about it and so every lvl 150+ in the game is gonna B-Line to the area to DEFEAT the Dragon Menace!! But the Idea is that the "Biggie" DRAGONS have also heard of the Careless Slaughter of their own and are Fianally going to Put a Stop to it!!
The Area becomes a War Zone, but then soon enough 2 or 3 "Ancient" Dragons Enter the Scene. These would be extremely powerful and would be able to hold the Zone against any Threat including the Higher-ups who "came to the rescue"!!
(you GMs could have a blast with this. Imagine all the players fleeing before you!!!!)
Soon the Zone Become Effectively "held" by the Dragons who destroy a few Buildings Permanently and then Something VERY interesting Happens... The Lead Dragon Speaks and anyone in the connecting Zones; including Athens, because of the Wompah; can hear it! The Message would call for a Few of the Respected Leaders of the Guilds to Enter Camelot for a Meeting or a Summit...
(sometimes in RPing the Players aren't supposed to win, only to Prosper..)
The Lead Dragon (give it a name like TiaMat and 5 to 7 heads) Would warn that any further Senseless Abuse to its Kind in the Future would not be tolerated; and would be met with Even Harsher attacks on further Player Settlements. Of course Dragons arent stupid and Would Expect the Leaders to Call for some sort of "Legal Documentation" to be worked out amongst the Players to effectively eliminate Further Atrocitys upon Dragon Kind. Also a few missions (Giagantic Multi task type) would be handed out to Various Mission levels to "Make Amends" to the dragons for their misery....
What Happens from there would; of course; be up to the Players (and IMAGINE the possibilities!!!)
