Hi Everyone! I'm new to stellaris and for my first campaign (on ensign difficulty IIRC) it seems I've triggered some sort of event chain from a blackhole - it keeps mentioning the worm.
Anyway, I managed to get a few scientists killed, 2 science ships and got one back, and also I explored a temple. I was getting some pretty bad vibes but I'm also roleplaying as a inquisitive and xenophilic human race so I just kept going forward. Then some guy attacked me (apparently one of my admirals from the future) and I got really nervous - he spoke about some sort of time danger. Anyway, I'm guessing this event chain will end in some gigantic fight/battle, so what sized fleet should I have? I'm the most powerful empire (except for the fallen empires), but I haven't gone to war with anyone major yet and I've yet to try my hand killing leviathans i've found (minus the space hivers). Any tips on what to do first this event chain? I'm open to spoilers, though if possible I'd prefer to keep some element of surprise
