Viewers

Canon

Viewers are a humanoid with many cat-like characteristics: more body hair, cat-like facial structure, fangs, and cat-shaped pupils. They are also like psychics, but “instead of seeing with their minds, they see with their hearts.” Their abilities shown in the miniseries are healing wounds (accelerating a body’s natural healing), empathy (reading people’s emotions by touch), psychometry (psychic vision by touching an object associated with someone else), precognition (seeing the future), and post-cognition (seeing the past). They are able to share their visions with other by touching a reflective object.

The Sorceress collected them and used their powers to foretell the future and to interrogate prisoners.

My Fanon

They are called “Viewers” by the humans, but have their own name in their language. They translate their names best they can because humans can't speak their language, or they take a name the humans bestow upon them to use. They all have a base ability in healing wounds, empathy, psychometry, precognition, and post-cognition, but each have individual strengths in different skill sets. Viewers cubs can’t stay around humans for long periods of time because they haven’t learned how to separate personal emotions from the emotions of others and it can drive them mad.

Viewers have an informal foster care system within their tribe to care for orphans. If direct family members cannot take the orphan in, another set of parents will.

And because people have asked, interspecies sex is possible but it produces no offspring.
