If you're already in Cets pyramid and you're not having any trouble, you've done it right....
You can always run around and develope you're crew,
after you finish of Cet. The only thing you
can not do (after Cet) is go back into the pyramid.
You can also 'Reset Adventures', once you get back to Valeia and start all over. You lose you guild memberships and
all Quest Items, but you keep your skills, stats, gold and gear.
