Did you herd those lightning moles back underground? You should hurry, the direct sunlight isn't good for them!”— Geologist, The Precursor Legacy
The Geologist is a character in The Precursor Legacy. She is a young woman studying the geology of Rock Village and the neighboring Precursor Basin. She is distinguished for being the discoverer of the lightning mole. When a band of robbers invaded the Basin and scared the lightning moles out of their nesting holes, the Geologist tasked Jak and Daxter with the mission "Herd the moles into their hole", during which Jak had to chase the moles back underground, as they were too blind to find their own way. She offered Jak a power cell in exchange, and additionally asked them to bring her ninety Precursor orbs for research supplies.
The Geologist speaks with a distinct English accent much like the Explorer, and has an evident love of wildlife. She has red hair and wears clothing typical to the outdoors, with a large torchlight helmet, a teal-blue aviation helmet, gray tunic with a teal-blue vest, and brown pants.
