You share an instinctive rapport with a specific kind of creature.
You can ask questions of and receive answers from creatures related to the listed creature in your ancestry’s entry (for example, “bat,” “lizard,” “squox,” or “turtle,” as seen in Entu Colony).
You can use the Diplomacy skill when interacting with those creatures, as long as they are capable of understanding you via this ability.
In ambiguous cases (such as “bearlike” vs. true bears, or cyber‑augmented variants), the GM decides which creatures count as “related” for this feat.
