In keeping with the 'Campaign Elements' series, this product provides a location and some reasons for going there. Like many, it has the potential to be an enduring location in your campaign, with characters wishing to return at a later date.

The concept is simple. It's a ruin of a castle deep in the forest. It is home to the ghost of a competent fighter who when alive kept his martial secrets to himself but since his demise is now willing to teach... but only those he deems worthy of his instruction. That is one reason why characters might wish to visit the place, although other reasons are also provided.

The layout of the ruined castle is provided as are a remarkable number of monsters - the reason for these will become apparent to inquisitive members of the party. There are notes on running this adventure, which includes characters being required to engage in single combat (always a bit tricky - what do other characters do?) as well as suggests for other uses for the material presented. Maybe an NPC has been here and uses one of the specific and unusual martial skills taught. Or the monsters turn up elsewhere...

It's a neat package with plenty of potential... as well as a good stand-alone piece to drop into a campaign at a convenient moment, to be run without need of extensive preparation time.
