Again we have the Foglios to thank for the benificence of another page
of the adventures of Lady Agatha Heterodyne, the eponymous Girl Genius.
Two in-jokes grace the page, neither of which I managed to note myself,
but which were spotted by other eagle-eyed readers in other forums.
The wand borne by Zeetha bears upon it the legend "Ral Partha", which
recalls to us one of the first firms which made metal miniatures for the
players of Dungeons and Dragons and its successors and imitators. Many
of their figures had swords, staves, and wands that were oversized,
making the legend appropriate to Zeetha's wand.
The Prince's castle has a general shape suggestive of a building which
is part of the Fermi National Laboratories in Illinois (Fermilab).
