Ulf paid for "two weeks of research ($800) for a sage to see if there are any legends about the "moon doors," giving the description of the phases of the moon on the doors, as well as any info for any "little people" who might come from the moon."
Here are the results of that research. I'll blog these as well for easier retrieval later.
- the moon is somehow impenetrable to magic. It's quite far away, making direct casting impossible, and indirect spells such as Divination fail completely. What little information is gathered from such spells is verifiably wrong, implying only critical failures and no successful divination.
- a very old rumor that went around was that delvers had found a way to the moon - one claimed to have spat or urinated (accounts vary) down on Stericksburg from above and either caused a huge rainstorm or filled a pond when his spittle reached the ground, depending on the account. This account is widely discredited.
- those delvers claimed the moon was populated by tiny green goblins with vast supplies of moonstones.
- the same delvers claimed the moon was edible, or that the green goblins ate moon rocks.
- those delvers and their names seem lost to legend, and it's not clear if they ever really existed. It's considered most likely that, if they even existed, they merely encountered some moon dwellers in Felltower and either learned of the moon or made up stories to explain their encounter with the green goblins.
- the shape seen on the moon with the naked eye is said to be the outline of a giant moon rabbit wielding a forge hammer.
- keen-eyed observers have occasionally seen lights on the moon, which is variously ascribed to some flash of the rabbit's forge or as being the twinkle of the gemstone eye of the moon rabbit.
- the doors described clearly have the moon phases scribed on them. The moon phases are left-to-right, in order that they travel. This implies a left-right writing system, if such exists.
- lycanthropes, especially wolfmen, are associated with the moon and may come from the moon or dwell there.
- beyond the sphere of earth is the realm of the elder things, or at least of some of them.
- even the immortal elves know little of the moon, except that evil beings dwell there. It's not clear how they know, and they are not inclined to share.
Little is really known about the moon, thanks to the impossibility of magic reaching it and the total lack of credible, verifiable travel to it.
