I don't understand Halo 5's legendary ending:
In the legendary ending, we see a Halo, which seems to be next to some planet other than Earth, starts glowing alongside the back.
What does it mean, exactly? Does this mean Cortana has gained control over that installation, and that it's under her control, or is it just another Halo that has reactivated?
In the regular, we learn that Exuberant Witness forces Cortana and her Guardian out of Genesis, but we learned that Cortana and her Guardian have already found where the Infinity's location is and has started to wreak havoc among the planet where the Infinity is. Since that planet is nowhere near the planet depicted in the legendary ending, how is it that Cortana can gain control of that ring as well?

At the end of Halo 5, the UNSC Infinity begins doing random jumps in order to escape Cortana. This parallels the beginning of Halo 1, where the Pillar of Autumn performs a random jump in order to escape covenant on Reach.
In Halo 1, the random jump leads the Pillar to discover the first Halo Ring. It's very likely that the parallel between Halo 1 and Halo 5 of "random jumps" to escape a threat has led the Infinity to discover a new Halo ring in the same way that the Autumn did.
In any case, the point of the legendary ending is that there are more Halo installations than were previously realized.
