The Screecher, a Sith of female gender, resided within a cavern called Screecher's Reach located on a planet that remains unknown. Her distinctive screeching earned her the moniker by which she was known. According to local legends, she was believed to be either a phantom or a mere illusion.
By the year 32 BBY, the Screecher had already established her residence in Screecher's Reach for an unspecified duration.
The Sith Mother assigned Daal, a Sith apprentice, the mission of killing the Screecher. Daal journeyed to Screecher's Reach, accompanied by three companions. Upon entering the cave, the Screecher announced her presence. Baython, Keena, and Quinn fled in terror, but Daal chose to remain and confront the creature.
The Screecher launched an assault on Daal, who attempted to flee by scaling the cave walls. However, the Screecher seized her ankle, attempting to drag her back down. Daal then employed the Force to loosen a sizable rock from the cave wall, which she then dropped onto the Screecher. This action caused the Screecher's lightsaber to fall from her hand and forced her to the ground.
The Screecher tried to recover her lightsaber, but Daal seized it first. After a brief struggle, Daal managed to prevent the Screecher from reclaiming it. Daal activated the lightsaber and used it to defeat her.
