ascian (I searched for previous usage of this, but results were confusing. Any way, I'll bet nobody remembers it.)

Definition: one that has no shadow; specifically : an inhabitant of the torrid zone where the Sun is
vertical at noon twice a year

Example sentence: "They are mysterious to me, these ascians," said Balrone, "for twice each year, at
the very instant of noon on the equinoxes, their shadows vanish, and they appear to me to be
enchanted."

Did you know?

When 17th-century British author and philosopher Nathanael Carpenter wrote a
two-volume Geography in 1625, he occasionally indulged his poetic persona, including
within the pages of that volume some original verses. But it was no mere flight of fancy
that prompted him to call the inhabitants of equatorial lands ascii. He surely knew that the
word (which is the plural of ascius) came from a Latin term for "those without shadows" (it
traces from the Greek a-, indicating absence, plus skia, meaning "shadow"). He also must
have known that there was nothing mystical about such shadowlessness. At the spring
and fall equinoxes at the equator, the Sun is, for a few moments, directly overhead, and
nothing below casts a shadow during that time.
