I had the Orb of Draginol on TWO different Worlds in a 0.55 game, and I built the Orb of Draginol on the surface of one of those Planets (that was close to my Home World in that game), which gave me an Artifact called the Orb of Draginol.
Then I activated the Artifact, and I got what looked like a Space Monster Hive that was labeled (or named) "Tear in Space" and 4 Fleets of Space Monster Ships. I think that the Tear in Space links to the Pocket Universe. (Sort of like the old Master of Orion 2, where we go to Antares and have the battle to win the game). Each of the Four Space Monster Fleets had 11 ships with a total of 50 Guns and 8 Armor for each Fleet.
In that game I had TWO Worlds that Each had a Orb of Draginol on them. So I suspect that we can see multiple Tear(s) in Space.
Probably linking to the same Pocket Universe, so "MAYBE" they can serve as a shortcut between different Tears in Space via the Pocket Universe, if we can use the Tear in Space without killing it? One near my Home World , another in a different Home Sector for 2 other Races.

Can you get to that link to Discord from a Forum Post (message)?
If not, got to the Discord and Search for "Tear in Space" for screenshots of what I saw in that 0.55 game (fairly recently, i.e. about 3 weeks ago, before 0.60 was released). However, most of my military was in other Sectors, so I was not ready to fight what came out of the Tear in Space.
I tried clicking on that link and it seemed to work just now.
I did NOT try to fight those Space Monster Fleets or try to use the Tear in Space. So what comes next I do not know (yet).
added: I only activated it so I could see what kind of hostile Fleets would come out of it, so I could design and build my ships and Fleets to fight them. I was not ready to fight them in that game. And not much later, 0.60 started, so I never fought them for real, in that game.
Sorry for only giving you an incomplete answer on what to expect from the Orb of Draginol, but I at least did not spoil it for you too much. Just some hints. There might be more yet to see, particularly if it is possible for multiple Tears in Space in one game.
