Tarentek waited patiently on the ledge. As long as he did not move, he did not have to worry about falling, and he would be less likely to be discovered. His robe could blend in rather well with the rocks, so at a distance, it would be quite difficult to detect him. While he waited, he had time to think about how he was going to word his warning. From his impression of Onyx, he got the sense that her race was prideful and isolationist. However, he had a feeling their leader might be more agreeable. Generally, it made sense to give the common person a strong since of pride and confidence in the group, but leaders tended to be at least a bit more realistic. They were responsible for their people's safety, so not only did they have to know what their people were capable of, but also be aware of and acknowledge their weaknesses. As such, their leader might be receptive to his warning. 

Once Onyx finally returned, Tarentek stood up and walked over to her so she could pick him up once more. "I suppose so. I've had plenty of time to think about what to say. Let's just be quick; I would like to avoid the rest of your kin until your leader can protect me."
