"Morkendaine" is a 16-page dungeon for 1st and 2nd level characters by Jennell Jaquays, published in The Dungeoneer #9 (January-February, 1979).

An abandoned manor house and its cellars are described, as well as the two-level dungeon beneath.  A new monster, the shadow giant, is included.

The Lawful god Asura is loosely based on the Hyborian Age deity mentioned in Robert E. Howard's "The Hour of the Dragon" also appearing in Gods, Demigods & Heroes.

Many of Jaquays' classic design elements are apparent, with enough interesting material for several game sessions.

AD&D:

The adventure was published after the AD&D 1e Monster Manual and Players Handbook were released, but before the AD&D 1e Dungeon Masters Guide was available.

Many of the monsters are drawn from the AD&D 1e Monster Manual, and various spells are likewise taken from the AD&D 1e Players Handbook.

A base AC 10 and specific armor types from the AD&D 1e Players Handbook are used, in addition to the nine-point alignment system.

The Dungeoneer:

Jaquays also incorporated material from earlier issues of The Dungeoneer, including gremlins from The Dungeoneer #1, Circean non-magical potions from The Dungeoneer #2, and vorpal bunnies from The Dungeoneer #4.

Underworld Oracle:

Underworld Oracle was a short-lived D&D fanzine published in the UK.  Jaquays makes reference to "On the Rack" by Low Nisbet, an article published in Underworld Oracle #5, which provided mechanics for torture.
