Fold physicist
A physicist working from a remote research array on Ravel. Serrin prefers concrete explanations to mystical language, especially when the readings make no sense.
In the world of Vesper
Serrin is associated with the abandoned research array on Ravel, a moon of Khepri. His role is to translate impossible readings into a concrete problem the pilot can understand and act on.
He is impatient with mystical explanations. The writing gives him ordinary comparisons and immediate consequences, keeping investigation connected to the danger facing Vesper rather than an endless glossary.
