That is the system Infinite Factory per Cravers questline. Even players can get that system when playing as Cravers and to my knowledge only the player with the quest can see that system.

Odd...
Is it going to go away when I capture their last systems? Or does it count as a system for them?

It's definitely a pain to have to leave a fleet back there to fight off the new ships.

EDIT:
What do the neutral ships mean that spawn there?

It's been a while since I've played Cravers so I don't know for sure off the top of my head. That said, if the system itself is White and not the color of the Craver faction then it should not hinder you from dealing with Cravers. You might be barred from invading the system but you should still be able to destroy the planets with a Core Cracker or system obliterater.

The White ships are part of the Cravers quest. Consider them pirates that *should* not target you in any capacity and are only there to serve the quest goal of the Cravers.

Okay, thanks.

Just to clarify, It's just the ships I can see, there is no system visible, even though it's inside my influence.

There very much is a system there. It's just that it will never appear until the Craver faction decides to take over the system. If it remains neutral it will never appear to other factions.

Cool, thanks!

It's linked to the Cravers' faction quest: while the quest is underway, the system is only visible to the Cravers, and when the quest is completed, it becomes visible to all players. If you're playing against the AI, which often struggles to complete its faction quests—in a timely manner or at all in some cases—then it's likely that the Cravers AI has the quest but hasn't completed it yet. If it can be completed, the system will become visible to all players, who will be able to interact with it normally like any other system. It's somewhat similar to the Sophons' Incandescence system, though that one is available to all players right from the start; for the Cravers, the quest has to be completed first, but it will appear for everyone.
EDIT: Unfortunately, if the quest can't be completed, the only way I know of to fix it is using the modding tools command. :/ There may be other ways, but if there are, I don't know 'em!

Alright. I've not tried playing as Cravers yet so I'm not familiar with their quests, but I have played as all the others except I'm not using the UC and Nakalm DLC yet.

What was curious to me is how they kept creating ships there. Maybe I'll give Cravers a shot to find out.

It's a fringe problem that wont pose a great boon to the player if it ever comes up. Cravers have a mechanic called depletion that will ruin systems over time. If left to a single system and no reliable source of slave labor then all of their production will plummet rather violently. Depleted planets only generate half of their normal FIDSI and any Craver population will add no bonuses on their own to a planet once depleted. In order to brake even you need a population of 1 Craver to 4 others, or more to even hope of getting back into the game with a single system. This will even have the knock on effect of tanking approval as so many slaves reduces FIDSI output further unless you know how to manipulate Hero governors to mitigate the problem.

When you do pick them up for play take your time with them, watch how depletion works and plot out ways to mitigate it in the short term, then maximize it for mid/lategame. Micromanagement in the right places will go a very long way toward winning with them.

Thanks! I never got around to playing the Necrophages in Endless Legend either, probably something about having to keep pushing forward to stay caught up, where I usually play races that can build taller and get an epic economy then press outward. I'll probably get around to Cravers though, they do seem more interesting.

Necrophage is actually one of my favorite factions, just behind Broken Lords. You would not think it but Necrophage are ment to be played EXTREMELY tall. Depending on the content you use in your game they also have access to the single most broken mechanic in the game. You might have seen people talking of the Deathball, a single army with around 30 troops in it that can steamroll most armies and cities with relative ease. I managed to discover how to bump that number up to around...a modest 200, all using only the vanilla game mechanics. Holding around 3-5 cities maximum to keep empire costs low gives you a very firm footing to do more or less whatever you want with the rest of the game from that point.

On top of all those other issues, Infinite Factory comes out as a Tiny (or maybe Small, I don't quite remember) Barren planet—generally without any special resources, if I recall—so the population capacity is quite small and the FIDSI output is rather minimal to begin with, even for Science and Dust. It's a neat oddity and fun to pursue if you're not serious about the match (maybe you've already won and are just continuing for kicks), but it really won't be a noticeable loss if it never shows up, and you won't miss much of anything by not being able to capture it. The bigger problem it poses is when you can't finish off the Craver faction because you can't see it! (Which I hope isn't the case in the OP's game.)

That's what my concern was. But hopefully it seems it's not visible until they own it so that wouldn't be the case.

I was trying to get better at Hisso in that round and had set supremacy to the only victory allowed. Around turn 300 I decided to start a different round, since by then I'm sure another victory would have been reached by the AIs. I was close to defeating Hisso but didn't get to actually test it if they count as defeated.
