Ka-Zar’s brother, Parnival Plunder, is stealing Savage Land Vibranium when he comes across a mystical bone. Shanna and Zabu get captured trying to stop him, Ka-Zar goes to rescue them, and Parnival dies in the process. And then the mystical bone teleports all three of the heroes into outer space where they get involved in a space battle. Ka-Zar is way out of his element, obviously. But we learn that Savage Land was created by an alien race called the Nuwali.
There’s a note from editor Denny O’Neil telling readers that the book is cancelled but will return as a “regular” (i.e., not direct-market only) book. That doesn’t happen for many, many years.

Here’s the final panel:
He won’t get another series until 1997.
