Constrictor Bloodline

"While the magic of the Naga belongs to the Cobra Bloodline, the Constrictors are the priests and mystics of the race. Constrictors are extremely rare, even more so than the Cobra, but their wisdom and connection The Akasha is valued by even the most jaded Asp warrior. There is no question that the Constrictors' understanding of The Akasha is far superior to all other Bloodlines, naturally leading to their roles as priests and religious leaders. They also are valued at times of stress for their ability to plumb the depths of the Akasha and summon forth memories from the race's past to aid in the solving of modern dilemmas.

"Constrictors are almost without exception somber and conservative. They take their duties very seriously and are not given to flights of fancy or pointless adventuring. Those who are found wandering in Rokugan are typically on a very specific quest or mission that will in some way benefit the Naga as a whole." -(D&D: Oriental Adventures: Rokugan p28)
