Ymir: That’s a pretty big question. A lot I guess considering we’re talking of trillions of people. There would be the merc and other gun for hire of the galaxy first, they aren’t “radical” proper but could execute criminal endeavor for money if paid by any of the true radical.
Yltel engineer: There’s also lost Karaks legends. It’s a group among the pirate made of people who came from the galaxy beyond the observable universe in a portal like the one we’ll install here that was stolen. It is said that they seek a similar portal to make their way back home.
Ymir: Even if it was true that some Karaks are in our galaxy and were looking to use an intergalactic portal they would be the last to want this project destroyed. They’d be more looking to steal it.
Ymir: Also there would be some from my people, despite the great efforts made to integrate we still have xenophobic extremists, remnant of the kind of people that lunched the Yltels supremacy wars. Us improving relation with even more races from beyond the portal is an heresy to these people. But people more acquainted with this topic would be better informed than I am. If you ask the Vosendy high prosident, she could probably get you in touch with someone from their intelligence service.
