[Shai]

You mean Unulkahai and Elidibus.

Unulkahai is an enigma, we know little about him, but is key in the Warring Triad side quests.

Elidibus is the high ranking Ascian in white. Claims he's a good guy, but I think he's full of it.

Unukalhai is the name of the brightest star in the Serpens constellation.
This is the [hidden] 13th constellation of the Zodiac (FFT) that is only peripherally connected to the path of the sun.
in Final Fantasy Tactics, this Constellation was represented by the mage Elidibus who was also a Lucavi that summoned Zodiark.

Draw from that what you will.
