Summary

After theEnterprise’sfive-year mission,Star Trek’sMister Spock left Starfleet to study Kholinar–and now his reason for doing so has been revealed. In 2021’sStar Trek: Year Five #21, Spock, stranded in Vulcan’s distant past, finds himself face to face with Surak–the founder of modern Vulcan society. Spock’s encounter with Surak greatly affects him, stirring both his human and Vulcan side, setting him on a path that does not involve Starfleet and theEnterprise.

Star Trek: Year Five#21, written by Brandon Easton and illustrated by Silvia Califano, finally explains why Spock left Starfleet. In the previous issue, Spock was thrown back through time to prehistoric Vulcan, to a time before logic. Spock arrives in the midst of a civil war, between those who follow Surak, the founder of the philosophy of logic, and the remaining holdouts. In a clear case of “do not meet your heroes,” Spock grows disillusioned with the historical Surak. Surak points out that Spock has yet to reconcile his two halves, Vulcan and human. These words are burnt deep into Spock’s brain, or as he puts it, “a bruise on my consciousness.”
