From the introduction:
The Obelisk is moderately large outdoor adventure with a small attached dungeon for a party levels 1-3.
This adventure was occasioned by my players deciding to take a lark into the wilderness rather than exploring Patrick Wetmore wonderful megadungeon the Anomalous Subsurface Environment (ASE). It's my own attempt to create another, smaller adventure location that seems reasonable within Pat's world. It contains several elements (guns, ancient technology, God's eye's) that won't make sense outside of ASE, but I suppose it could be run as a simple graveyard based cult-smashing expedition in with a little modification. It's also an attempt at an adventure in the old style of the TSR products I grew up with, or at least as I remember them played in the hands of murderously inclined pre-teen boys on lazy Summer afternoons. The encounters within are not scaled to allow a 1st level party to win in a stand-up heroic fight. There are encounters, and even individual creatures (especially the special random encounters), quite capable of slaughtering a party within a couple rounds, but this is how it should be, as they can be avoided or negotiated with.
