I’m not entirely sure if this was the first series with the character of “Ivar”, but that’s part of the magic of this particular Time Travel series in which an Immortal lives forever, but in a non-linear timeline, something that was briefly touched on by Star Trek: Deep Space Nine, but not really explored as much as this Timewalker series does.
It’s fantastic, it was a good bundle to pick up at a con for only $4!
