Deception Pass

Looks can lie as well as words.

Magical minotaurs? Mutant giants? Vampires? One or more of these is preying upon the caravans, and you're going to stop them.

A band of ogre magi took over an abandoned dwarven stronghold and have started ambushing merchant caravans. Their leader, Krugii, wants to gain enough power to eventually control a kingdom. In his quest for power, he has bonded a young bronze dragon and has accelerated its growth.

The ogre mages all have different personalities and different forms that they prefer to polymorph into. The PCs are hired to take a caravan through Deception Pass and protect it against the random monsters that have been marauding lately (actually ogre mages in disguise). After protecting the caravan, the players track the attacks back to the stronghold of the ogre magi and clear it out.
