Origin

Star Trek Canon Special Note
Not everything listed in the origin is Canon.  That is because only television shows and movies are considered canon for Star Trek.  This being a comic website there are many things here that are not canon.  So unless it is contradicted in film it should be listed as part of the location origin.
 
Talos IV is the location of the Talosains.  Going there was the last death sentence on in the Federation.  This is due to the power of the native Talosains to make humans see and believe any fantasy as if it were real.
