An alien life form penetrated the defense network of my fortress this morning.
Its posture within the secure zone indicated that it realized its fatal miscalculation.
Security forces encountered little resistance, and so were able to be merciful. The invader was extracted and banished to a dirt pile outside the perimeter. No casualties were reported.
An after-action review board will be convened to assess the protective measures that are currently in place, and will recommend adjustments to security protocols as necessary.
