So that means the "present" portions are late 2381 or early '82? Which would be less than a year after Destiny takes place. Though clearly we're dealing with a separate timeline here.
It is a comic, so it will probably have nothing to do with the novelverse.
On the other hand who is to say that all Borg were eliminated. There may be some still around (some who were not around when Destiny happened). By the way, is this discussed somewhere?
