Ptaclusp IIa

Ptaclusp IIa (Two-Ay) is one of the twin sons of Ptaclusp. He is an accountant. During the building of Ptaclusp's Folly, he invents both algebra and calculus as well as quantum accountancy to deal with the wages bill.

During the latter events of Pyramids, he becomes "dimensionally maladjusted" and flat as a shadow, but returns to normal with everything else.
