This adventure, for characters of 5th-7th level, sends the party into a ruined keep that's crawling with undead where they'll have to find out what's causing the problem and face a tough decision between doing the right thing and lining their own pockets rather hansomely! The Players' Introduction explains that everyone knows about the lich who lives up there and so stay away, but of late it seems impossible to bury your dead hereabouts without them springing back out of their graves!
The GM Background explains what's going on and who is really behind all the trouble. Moreover the party receives not one but two job offers to clear out the keep... one of which is from the lich himself! Needless to say, the objectives of the two job offers are somewhat different, and whichever one the party decides to take, the other lot are bound to be annoyed and liable to cause them problems in the future.
The adventure begins in the bustling port of Heathwyck, which lies in the shadow of a mountain known as Covenant Hill. Here the party receives their first assignment from the Temple of Light, who want them to steal the lich's phylactery, the artefact that empowers his abilities to raise and control undead. The locals greet the news with delight, and start treating them as heroes even before they depart on their mission...
It's not too far to the keep, even if it is a bit of a climb and the road is overgrown. The keep is well-described and there's a good plan (but it's not player-friendly, you'll need to sketch something out to show them) - and the place is crawling with undead. Should the party study what they find they can discover the truth of the matter, which might change their opinions as to what they ought to do. A new form of undead and the phylactery itself provide the customary new monster and new artefact.
It's a fairly straightforward slog of a fight against a large - and I mean large - number of undead, although the twists and turns of who's actually doing what and the conflicting job offers make it just a little more than that. There are a few errors in the text (mostly spelling, but one bit that doesn't make sense - fortunately not an important one), otherwise it's presented clearly. A good session-worth of fighting to drop into a campaign. And of course there's the undying emnity of someone to contend with thereafter...
