As a rule I stay out of conversations about what is and is not in a book...however, in this case I'll make an exception.
I debated for a long time putting in stats for the Vorlon ships, mostly because I thought it would be amusing to play out some of the 'foreground' battle shots headed into "Into the Fire". Sweep in, hit some Vorlons in the nose, run like hell.
On sober reflection though, Sheridan is right. Nothing the younger races can throw at the Vorlons can destroy them. We are doing good when we inflict some damage (using Minbari weapons aboard a hybrid Minbari/Vorlon warship) to basically unmanned listening posts. We can damage them (witness the use of the Gaim warheads) if they are not expecting it, but destroy one in an open fight? Not on our best day.
Even if we could kill one ship Vorlons fly around in giant packs. Let's say an entire fleet mobbed one of their little warships and cut it apart. You can kill just about anything with a sufficient application of force. What are the other 450ish Vorlon ships doing while you kill their friend? Sitting around drinking tea and discussing how hard it is to use a three-edged sword?
Then you get into the story reasons for not including the ships. It doesn't really matter how tough their ships are. A hell of a lot tougher than ours is all that counts. We CANNOT win a fight with them. That's part of "Into the Fire"'s point: Sherdian and the younger races reject and defy the elders knowing the possible consequences and accepting them. They can swat us aside like bugs if they are so inclined. But they don't...because in the end, it's not about guns. It's about ideas, about hopes, about making the world a better place because you can. Its about letting go when the time comes, which is one of the hardest things you can ever ask anyone to do.
So no. No Vorlon ships. Sorry. If your players run into one, just smile and let them do whatever makes them feel good.
Think of it like being attacked by a one year old. You are never in any danger, but eventually you get annoyed enough to administer a little spanking.
Preach mode off. Lurk mode back on.
