The Tomb of Sigyfel is a well written, clear little module that does what it sets out to do: Serve as a short introductory adventure. The overall quality is good with no errors or conflicting information. The map is well drawn and lends itself to use anytime a quick side trip might be needed. Although designed for Labyrinth Lord, I will be using it for AD&D 1e with no problems.
This was a well written introductory adventure for Labyrinth Lords. It played well and was enjoyable. Though short it is a decently designed dungeon. Any group that explores it should have a good time doing so.
