After getting an alt through all the crap to get too this part of the chain, there are some things many of you may want to know before wasting your time on this.
I started expecting too be able to spawn as many dragons in the keep as I wanted, so that anyone who entered would just get owned. Causing total chaos.
After doing it heres what happens:
First off, you can only do it once. Because after you do it bolvar and the lady are still in a weird position(and lady onyxia is stuck in dragon form) and it won't let them do the event again until a gm resets it, or the server resets.
Second, its only like 8 level 61'ish dragons. and Bolvar DID attack them. Meaning that even if you could get the event too complete a second time, by the time you got back from walking through the city on the escort they would all be dead from Bolvar alone.
Third, A single level 70 could probably kill them alone... and usually, even outside of primetime you can find multiple people standing around.
So yea, don't waste your time, its not all its cracked up too be...
