How Would you defeat a creature that eats a full grown dragon for a meal?

As if the perils of everyday travels and adventuring weren't enough, those that hunt for the Dragon's Eye Diamond also have other foes to contend with. Because this diamond is reputed to contain the power over life and death, there are those that will attempt to have this power as thier own for whatever nefarious deeds they have planned. Then of course there is the dangers of locating this myth, they will have to search some of the most treacherous of lairs and ruins know on Abeir-Toril...including the dens of dangerous beasts, such as a dragon...or worse.

What's more the search has drawn attention of perhaps the most infamous of adversary,

The Red Wizards of Thay.

Who among you is brave enough?
