Dangerous if you want to get into the thick of things and actually do stuff for corpos and the like. Insect spirits, shedim, random heavily armed grunts, jacking into a system then getting yourself splattered over a wall because you underestimated their cyber-security, the works. It's not unsurvivable, but it's the type of setting where you should fear the people who have lived to an old age where men die young.

Includes the likes of Harlequin, the Great Dragons, and the Horrors. The first two have a wide "Do not fuck with" sign attached to them by pretty much the entire setting but many of them are genuinely trying to save the world in their own ways (even if a few of the dragons are smug assholes about it) and whilst Harlequin is the definition of a dour knight and mild cynic, he's also the one who has been most effectively keeping the Horrors out of the Sixth World for thousands of years. Generally stay out of their way and they'll stay out of yours.
As for the Horrors, you'll hopefully never see them. If you do though, then it means that the world is ending and everyone is going to get eaten or worse.
