From publisher blurb:
Playing a Paladin can be an enjoyable experience especially with their vast array of powers and special abilities. One of their most overlooked abilities is their calling for a bonded mount at 4th level. Several scenarios are available for this "calling" including dreams, quests, etc. in the books but I have yet to run across any published adventures for it. This adventure provides one such option for gaining the mount and utilizing the Paladin's recent ability to turn undead as well. While this is a short adventure, it gives the DM an option to go one on one with a Paladin PC and challenge him/her in order to win their steed and a little glory as well. I hope you enjoy it!
While this adventure is set towards a 1st/2nd edition AD&D for a 4th level Paladin, it can be modified to fit with most games and campaigns. It can also act as a 1st level adventure for a very weak or small numbered party.
