Sightings report rapid subterranean movement with sudden emergence at close range. Units typically engage in small groups, though several sightings describe delayed emergence despite clear surface movement above. Some sightings report individuals surfacing and remaining exposed without attacking before retreating below ground. Engagement is inconsistent in these cases.

Finally… something close to predictable. The delay shows up here too, but it doesn’t hold long enough to matter. Logging as standard behavior. Nothing here supports the patterns seen in the deeper entries. - Ward, Foundation Records
