"I am Princes Athanake."

The woman who stands before you is young and beautiful, attired in gowns of the finest green velvet, and bearing with calm grace a circlet of gold upon her brow. She captures, in the slightest gesture and inflection, a porcelain perfection that you had once believed to exist only in storybooks and myth. She is a princess.

"I wish that it were under happier circumstances and calmer skies that I welcomed you to Anach, so that we might prepare a royal feast and listen to your tales in better company. Unfortunately, that is not to be, at least for now. Instead of telling tales, I fear that I must ask you to make new ones.

"Three days ago Royal Miners discovered the hidden lair of the Wreyland Serpent, a black dragon who has ravaged our lands for as long as memory allows. All but one of the men who worked there were savagely butchered by the creature."

She delicately extends a hand to one side, and a waiting courtier immediately steps forward and places a scroll within her grasp. The princess, in turn, extends it to you.

"This is a royal decree, sealed less than a quarter hour ago, giving you whatever lawful authority is neccessary to prosecute our interests in this matter.

"I beg you. Deliver my people from this beast."
