The Place of Kastays was a tower on Aaris III where the Aaris Kastays tried to contain the evil of the Plaque of Victory. The scholar recorded the downfall of the Aaris civilization in a series of pictographs that emitted sounds when pressed.
Later, MS-133, an Imperial research group traveled to the planet to research the Aaris. When researching the ruins of the Place of Kastays, Grigor Tansad began to translate the pictographs and learned about the Aaris. They also uncovered the resting place of the Plaque of Victory, and its influence destroyed the team. The Place of Kastays was the site of Jelok's murder, seemingly perpetrated by a confused and paranoid Tansad.
