Bodo Baas stored the power known as Alter Mind within the Tedryn Holocron. This power, which involved manipulating the thoughts of individuals, was considered valuable by Baas. However, he also cautioned that it could potentially corrupt a Jedi, leading them towards the dark side. Furthermore, Alter Mind referred to the capacity to transmit a visual representation into someone else's consciousness. Frequently, this representation distorted their understanding of the world, or served as a deceptive image capable of swaying their actions.
