Thank you all for posting the extra information, I did not originally see the Eternal Bonding website which both clears up some of the questions but also infuriates me a bit.
I don't really understand why we had to book "reservations" since it appears as if everything is being handled by the game and not GM's or live people.

This whole thing seems a bit tedious actually, though I still want to do it, just maybe not right away. I'll wait and gather more information before I touch this. Far too many variables and if Im gonna pay good money for it, I want it to look right.
I do think SE should have made it so we could save the ceremony cut scene somehow in our journal though....
