Editing Jonathan Archer (section)

===Season 4===
After returning home in 2154, Archer helps a faction of [[Vulcan (Star Trek)|Vulcans]] fight an oppressive government on their planet. During this incident, he is the recipient of the ''[[Katra (Star Trek)|katra]]'', or living spirit, of the great Vulcan philosopher [[Surak]]. The ''katra'' is later transferred to a Vulcan priest, and Archer is left unharmed. This leads to the reformation of Vulcan society, and explains{{citation needed|date=October 2020}} why the Vulcans of Archer's time were so different from the Vulcans of [[James T. Kirk|Kirk's]] time. In the process, Archer becomes the first known Human participant in a Vulcan [[Vulcan (Star Trek)#Mind melds|mind meld]]. Since that experience, he has used that knowledge at least once: To assist [[T'Pol]] with conducting her first mind meld to gain information about who kidnapped [[Phlox (Star Trek)|Dr. Phlox]] (the episode "[[Affliction (Star Trek: Enterprise)|Affliction]]").

Archer is also involved in one of the first, and possibly most significant, treaties yet, being asked to escort Gral, the [[Tellarite]] ambassador, to the Tellarite-[[Andorian]] negotiations. En route, he and his crew run into the Andorian [[List of minor recurring characters in Star Trek: Enterprise#Thy'lek Shran|Shran]], a long-time friend/enemy/ally. During Shran's stay, [[Romulan]]s attack and cause the fragile alliance to crash to a halt. In the mix-up, a Tellarite kills Shran's lover [[List of minor recurring characters in Star Trek: Enterprise#Talas|Talas]], and Shran avenges her death by demanding the Tellarite who killed her to fight to the death. In an attempt to protect the fragile peace treaty, Archer takes the challenge instead and Shran is incapacitated. The alliance remains intact, and soon evolves into the [[United Federation of Planets]].
