Sorry, to answer your question, I'm not sure what else needs to be done, but I'm sure I need the broaches. I got the orb and the gesture and went through the two keeps of Black Spire but got out on the peninsula and it said my quest was in vain.
I must have done something in the wrong order, now I'm stuck. I went through all the dialog options. I think I have the same issue as in this post.
He says he edited the script. I wonder what needs to be done to fix it.
Could someone point me to a spoiler that includes how I can get the requisite training in using the portals system?
First post, enjoying the old fashioned RPG style of these games.
