We used to have the ability to generate an energy field that had a calming effect, allowing individuals to see reason.

STARK Are you serious? The Eidelons are remarkable mediators -- legendary for bringing the most intolerant enemies to common ground. 

CHIANA Scarrans aren't going to be reasoned with. 

PIKAL But they will... if... 

CHIANA If what? 

PIKAL OPENS HIS FACE. 

 PIKAL CLOSES HIS FACE 

CHIANA (to Stark; unsure) Is he propositioning me? 

STARK No. That's a very special gland. 

CHIANA Small. In a weird place. 

STARK It's an antenna to feelings, an inner eye. Am I right, Pikal? 

PIKAL Yes. And -- our history leads us to believe -- substantially more. 

CHIANA It gets bigger? 

PIKAL Not that we know. However, it vibrates. 

CHIANA Hmm! 

PIKAL We used to have the ability to generate an energy field that had a calming effect, allowing individuals to see reason.

CHIANA But... your little limp thing, it can't do the trick anymore? 

PIKAL Unfortunately not. Our control of the gland has been dormant for generations. If our ancestors are indeed alive on Arnessk, I can only pray they will somehow show us the way to reignite this attribute within ourselves...
