The Grey Palace and the Eminent Cathedral loom above Vornheim like a pair of claws reaching for the moon. Between the two of them, there is a square. In the center of the square, there is a well. At the bottom of the well lives The Wyvern.
The Wyvern of the Well is both wealthy and wise. For reasons now lost to history, each citizen of Vornheim has the right--once in life--to climb down into the well and demand the answer to one question from the Wyvern.
In exchange for this (always correct) answer, the Wyvern demands 700 gold pieces and will, in turn, ask the questioner one question.
What the Wyvern does with the answers thus accumulated from the people of Vornheim (or the gold, for that matter), or why it--being, apparently, omniscient--bothers to ask, is unknown.
Naturally, the questions asked of the Wyvern tend to be personal, local, and, of course, petty. How can I get this, will she like it if I do that, how do I get more whatever. It is conjectured that the Wyvern, knowing--as a consequence of its ancient, strange contract or curse--the innermost hearts of the people of Vornheim, despises them for the myopic schemers they are. However, no-one wants to blow their one question asking it.
Some philosophers speculate that the Wyvern is cursed to know nothing except the answers to whatever questions the people of Vornheim will one day ask to know and what they tell him. In which case it is likely that the Wyvern went mad long ago.
