In 1984, TSR published the module UK5: Eye of the Serpent. It was written by Graeme Morris, and illustrated by Tim Sell. It consisted of a 32 page booklet and folding cover with maps.
This conversion guide allows DMs to run the original module with 5th Edition rules and provides a reference sheet for encounters. It is intended for 4 characters of level 1, and may be played by one DM and one player.
To use this conversion guide you will need a copy of "UK5 Eye of the Serpent".
