The fifth of the official TSR UK modules, this is a bit of a different one from previous installments. This is an adventure designed not for a party or even for a solo player, but for a one on one game with one DM and one player.

Designed specifically for rangers, Druids or monks, you can either use one of the pre-rolled characters or bring your own 1st level character to the game.

The story is also a bit different than usual, you and some NPCs get carried by Rocs to the peak of a mountain. From that mountain you can spot the titular Eye of the Serpent, a lush island at the bottom of the mountain. This is your destination. So the adventure is a descent from the top to the bottom, with a number of events happening along the way from the Roc nest to sea level. With some cool art and an interesting system of branching story paths, it’s worth seeking out.
