The Anomalous Entity Research Division (AERD) is a highly classified and specialized organization dedicated to capturing, studying, and experimenting with entities that deviate from the natural order. Its primary mission is to systematically research entities that are either unordinary, anomalous, or inherently hostile, providing in-depth analysis of their behaviors, origins, and potential threats to society. The division operates under stringent protocols and employs cutting-edge scientific methods to assess the properties of these entities, ranging from physical containment to psychic and mystical analysis.

AERD's approach is multifaceted, blending traditional scientific techniques with occult and arcane disciplines. Researchers in the division use advanced technology to detect, subdue, and neutralize the entities they study, while also developing new tools and containment strategies to deal with increasingly dangerous threats. Its experiments may involve biological, magical, and psychological examinations, all aimed at better understanding the nature of these entities and their abilities. Despite the scientific approach, AERD fully recognizes the unpredictable and often dangerous nature of the entities they deal with, requiring constant vigilance and security measures.

The organization maintains a hierarchical structure of experts, including researchers, hunters, tacticians, and engineers, all of whom collaborate to ensure the safety of the world while furthering the understanding of these otherworldly beings. The entities captured and studied are often kept in high-security containment zones, and only the most trusted personnel are allowed access to the classified data on each subject. The AERD's primary objective is to prevent any catastrophic events caused by these entities while gaining valuable knowledge that could aid in future defense strategies or scientific breakthroughs.
