You establish a telepathic bond with a willing target, where both you and the
Target can speak back to one another through
Telepathy.
If you cannot see the target, and instead are reaching out with your mind, your telepathy can pass through solid objects, within some limitations.
Once a link is established it is maintained through Psi.
A thread of thought stretches between you, unseen yet unbreakable. Words form without sound, meaning exchanged in an instant. Distance fades, barriers dissolve—mind to mind, perception entwined, thoughts no longer bound by voice or space.
