ACB-3309
Description
ACB-3309 is an anomalous planet orbiting a celestial structure referred to as "The Pillar." It serves as the homeworld of a humanoid species designated ACB-3309-S1. This species demonstrates technological development comparable to Earth's mid-20th century and is nearly identical to humans, with the primary distinguishing feature being differences in ear anatomy.
Habitation
Urban settlements constructed by ACB-3309-S1 are predominantly located underground, though the reasons for this remain unclear. Observations suggest that some of these subterranean habitations extend to depths beyond the planet's Moho discontinuity.
Containment Directive
Should ACB-3309-S1 achieve interplanetary space travel, the ACB-3309 system is to be neutralized. To execute this directive, a superlaser is to be constructed on Pillar I or II to ensure the complete destruction of the planetary system.
