The Geisterdamen (en: Ghost Ladies) - also known as Weißdamen (en: White Ladies), Spider Riders, and Ghost Ladies - are an order of priestesses in the service of Lucrezia Mongfish, inasmuch as she is the manifestation of The Other. How precisely this state of affairs came to be is still unknown, although according to the Geister High Priestess Vrin, the seemingly-immortal Lucrezia has been their ruler for generations, reappearing in the Geister homeland at regular but lengthy intervals.
Where exactly that homeland is located is another of the very big questions. They refer to Europa as "the Shadow World" and were Holy Child," taken from them by person or persons unknown after Lucrezia left said child in their care. Led by Vrin, they made this trip through by a gateway device built by Lucrezia and then were by the gate's destruction by the rebel Geister Loremistress Milvistle. Milvistle also managed to destroy the plans for the Summoning Engine intended to be used to put Lucrezia's mind into Agatha's body, forcing Vrin and Aaronev Wilhelm Sturmvoraus to cobble together a barely-functioning replacement.As their names imply, the Geisterdamen are all female and ghost-white, with a number of similarly pale beasts presumably brought with them. The most iconic are their by The Other to search for their goddess's "giant spiders, of course, but others have been spotted, including what one might term a "Geisterdragon" and large beasts used to haul carts. At least some Geisterdamen are themselves or qualify as, for testing purposes. It is implied that they normally do not cut their hair; Vrin does so as a mark of shame following Milvistle's actions.
As the story starts, they have been roaming Europa for (unsurprisingly) as long as Agatha as been alive, leading to a body of hostile folklore among the natives they have encountered: claims that they steal babies, cause revenants, blight crops, and all the other standard ills that get attributed to the strange and creepy — though we've learned that the service of their mistress, and their aforementioned search for the Holy Child, may account for at least the first two of those, as well as the general dearth of female sparks in Europa. (Again, see above about the non-functional Engine.)They wear a white uniform consisting of a wrapped or lamina-style bodice with shoulder caps (no sleeves), and a loincloth; the High Priestess is apparently marked out only by a gold necklace. A Gilgamesh Wulfenbach from the Future has been seen wearing a similar outfit, as shown in the picture to the left, a fact apparently too strange even for much theorizing.
Among themselves, Geisterspeak". It is distinct from the common language of Europa and incomprehensible to run-of-the-mill Europans, although learned by the royal family of Sturmhalten ( , and by implication the late Prince). to communicate initially with Oslaka; there is an implication that he taught her a Europan language later, or they taught each other.

Semi-Canonical Information Edit
According to Agatha H and the Clockwork Princess, all Geisterdamen we have seen so far have apparently been members of a contingent of The White Elite, three thousand strong. The novel also has Vrin give a slightly longer description to Agatha of the Geister's home and relationship with Lucrezia, though not to the point of answering any major questions.
The Girl Genius Complete List of Absolutely Everybody! states under the Lucrezia entry that their home is near the "secret base/summer home" of her father Lucifer Mongfish.
