The Fester Lion's Den (5E)

From publisher blurb: Over the past 50 years, a fester lion has been preying on hunters and adventurers traveling through this stretch of the forest. It has been hoarding it’s favored food: zombies that it creates in a secluded cave. The following Casual Confrontation, The Fester Lion’s Den is for 4-5, 5th level characters, and uses the 5th edition Dungeons and Dragons Ruleset. It also introduces the fester lion, a magical beast that preys on mindless undead that it creates!
