Gribyam

"Human science report, log 42. Prolonged observation of the Doctor Halsey supports theories from New Alexandria that human females signal maturity by losing appendages. If my hypothesis be correct, soon the Doctor Halsey will release her spores, and spin a cocoon of rich meat-silk! Truly this is a very exciting time to be making science!"

- Gribyam on Catherine Halsey

Gribyam is an Unggoy member of the Swords of Sanghelios and a self-proclaimed biologist. In October 2558 he formulated an outlandish theory about human reproduction, hypothesizing Doctor Catherine Halsey's missing arm to be due to a natural biological process.

Trivia
His mention of "theories from New Alexandria" may be a reference to Catherine-B320, who was also missing an arm.
