[Warhammer 40k/Star Trek] An Eldar Craftworld is transported into Federation Space. What happens?

Greetings. I am the senior Farseer of a reasonably-sized Craftworld formerly local to what the humans call the "Ultima Sector" of the galaxy. Our world was recently attacked by those pitiful Imperials and, in our valiant defense, one of our noble Aspect Warriors breached one of their primitive warp drives and created a violent Warp singularity, dragging in our entire fleet. Miraculously, our Craftworld survived the travel through the Warp with minimal damage, and She-Who-Thirsts has not laid claim to all of our mortal souls. However, we now find ourselves in a peculiarly calm region of space, being hailed by a positively quaint little vessel claiming to represent a "Federation of Planets." The captain is a bald human who seems to be under the impression we're "some kind of Vulcan," whatever that means. My junior Seers have discerned that A) the Warp is calm, bereft of the influence of the Dark Powers or the Great Devourer, B) the Webway is entirely absent, and C) the Imperial Astronomicon is nowhere to be seen. Thankfully our considerable psychic powers seem unaffected.

I apologize for posing these questions in such a crude format, but given my unusual position I am certain you will understand. I must know: should I trust this little man? He talks of peace and seems well-intentioned, for a human. Where should we go? Are there other significant powers within these placid space? What do they think of us? Is our Craftworld safe?

Safe? Is ones craft world safe?

Depends on where you are. I'd immediately establish where in relation to the federation are you? 

Assuming you're in federation space, you're definitely not safe since despite their outward intention of peace they're literally at war most of the time. 

The federation does a mediocre job at best policing their own space so it's likely you could get poached by a borg, klingong or other mostly sentient hostile parties. 

I'd highly recommend finding one of the smaller planets somewhere in neutral space or possibly in the furthest corner of the galaxy. Buy time for as long as possible.
