Tsun Qel was a Yuuzhan Vong who belonged to the Shaper caste. As a Shaper Initiate from Domain Qel, he journeyed to Yavin 4 with the purpose of observing the shaping process that Tahiri Veila was undergoing. He informed Nen Yim, a Shaper Adept, that Mezhan Kwaad had dispatched him, and as proof, brought up the name of Yakun Kwaad, Nen's deceased lover and a past shaper apprentice. Having been persuaded, she shared with Qel all the actions that Kwaad and she had taken. The reality was, though, that Yal Phaath, a Master Shaper, had actually sent Tsun Qel to determine if they had committed any heretical acts.
