For centuries Castle Maw has withstood every siege that has come to its walls. Recently, however, the powers protecting it have been waning.
Sensing this, the wizards of the area have begun to swelll with ambition and greed. The first to capture Castle Maw would become a living legend...
But to capture it is not enough. Capture would bring glory... but watching your opponents hurl themselves by the thousands at your superior defenses--and wacthing them fail... that would be priceless.
However, it has recently come to everyone's attention that a vast network of caves is present beneath Castle Maw, which would give anyone who control them an advantage when it comes to a siege. A large cavern has been opened, discovered beneath a reflecting pool, which leads to this abyss.
(This variation of the Maw contains a vast underground, connecting the players via another two routes. The AI is significantly more aggressive.)
