Articulary Motion is the name of the odd behavior wherein Pinky
and Perky have been seen to swap places. Once every 100 years,
Pinky and Perky inexplicably reverse their positions in the sky
for one night. This was first observed and recorded in -201 EC,
again in -101 EC, and then once more in -1 EC. The particular
night during which this happens remains a bit of a mystery,
except that it has thus far been on Ulfsday. In the first
instance, it was noted as Ulfsday the 15th of Gomin of the year
-201 EC. In the third instance it was noted as Ulfsday the 8th
of Jole of the year -1 EC by Ralph Neocronin. In both cases, the
swap was only for about two hours. It is interesting to note
that the lights of Pinky were all muted, to the point of almost
being gone completely. There was still an occasional flash, such
as from a lighthouse, but even then, they were noticably softer.
Phylostarus noticed the first swap in -201 EC and made sure any
further occurrences would be noticed and recorded. Naturally,
these swaps play
