Tanadan
Jason was still not sure how Pera and Jen hadn't been able to figure out that he had been a halfling without him exposing his identity.
However, what he didn't know was the simple fact that all kinds of races existed and that it was quite common to come across extraordinary-looking beings.
There were also those that looked like humans, only to be different, owing to different body parts of unique traits.
As such, nobody could truly figure out that one was a halfling, except if one was able to use repulsive energies or affinities at the same time.
This indicated that one possessed a unique constitution that allowed the wielder to use these energies and affinities at the same time.
In the end, there were also other possibilities to be able to use multiple energies or repulsive affinities at once, and Jason just didn't know about it yet.
