For all that the specific types of darkspawn Hawke has mentioned don't mean much to Picard (though 'ogre' does at least offer a general suggestion as to what to expect), the overall image she paints isn't one that Picard would call ideal by any stretch of the imagination. It might possibly be better than a Borg invasion, but that's mostly because the Borg are singularly annoying when it comes to defeating them.

"It would certainly be a memorable arrival, if nothing else."

Not a good one, mind. But one that any new arrivals certainly wouldn't be forgetting in a hurry.
