Bio-Terrapax

Physical Attributes: The BioTerrapax is slightly smaller than its Terrapax cousin, with an average length of 20 feet, a beam of 10 feet, and an average weight of 6 tons. Despite being smaller, it retains the robustness and the hardened exterior characteristic of its larger counterpart, which provides it with a solid defense mechanism. It also continues to possess the same cargo and passenger carrying abilities, albeit at a slightly reduced scale due to its smaller size.
Unique Abilities: What sets the BioTerrapax apart is its innate capability to communicate via Bio-Electromagnetic fields. This is a rare trait not observed in the common Terrapax . The BioTerrapax can use these fields to communicate with members of its own species, Aurics, and any other individuals or species attuned to Bio-EM signals.
This ability makes it a highly valuable asset for SERG and similar groups. A BioTerrapax could function as a live communication beacon, sending silent Bio-EM messages across vast distances. Given its size and power, its Bio-EM field is potentially much larger and stronger than that of a human Auric, allowing it to broadcast signals over much greater distances.
Training and Communication: Training a BioTerrapax to communicate specific messages is a difficult task and requires an experienced Auric handler. However, once trained, the BioTerrapax becomes an exceptional asset on the battlefield. Its ability to send silent messages to Aurics across great distances would make it an essential part of any strategic operation, allowing for real-time, undetectable communication.
Given the rarity of this subspecies and the unique abilities it brings to the table, BioTerrapax is treasured, not only for its labor but for its communication capabilities as well. They are seen as a bridge between the spiritual and physical realms, embodying the ideals of a world where every living being harnesses their Bio-EM potential.
This subspecies' existence fortifies the concept of Bio-Electromagnetic communication, not only among the human population but also among the creatures they share their world with. The BioTerrapax serves as a testament to the extent of aura manipulation potential in this high fantasy universe.
