Refugees of the Desolation

From publisher blurb:

A Zero-Level Funnel Adventure
The Illucid Valley was once the most beautiful and fertile valley on the continent. Nestled within the protection of the Felhold Mountains, it was a haven from harsh weather and enemy attack. In a loud, thunderous flash, the valley was blown apart and laid to waste by an unknown source of extreme power. Now, weeks later, the food and water supply in your town has dried up and your only option is to flee the valley. Unfortunately, you will have to face the harsh climate and nightmarish creatures of the desolation to reach your goal. Will you become a victim of the desolation?
