Sattai was a defective Irken since the start as her PAK was somewhat glitched. That ended up in her starting more problems than any Irken has done. Fires, acid floods, exploding a Irken warship are examples. The Almighty Tallest wanted her gone, but they didn't want her dead either due to the fact that they could use her. They solved the problem by sending her to Surray to annoy him as his "apprentice".
