Dungeon of the Selenian Conclave is the second module from Starlight Games and Alessandro Dellamotta. Like the first, it's meant for B/X. While his earlier effort was for low-mid levels (4th or so), this is intended for 1st and 2nd level characters.
The premise is somewhat similar to Arsenal of the Warrior Princess, his first module, in that the party explores an abandoned wizardrly research facility. In this case though, rather than being for weapons research, it's research meant to enable travel to the Moon. While this is generally possible with a simple teleport spell in most settings, apparently not the author's. (I don't know about the Mystara moon, though I do remember that's where the Immortals had their city. It also has a second, invisible moon full of Japanese cat people).
