I think this Void stuff will either lead to us having to go stop an invasion in a far away land (likely Meracydia), or will result in us basically halting the Void stuff for the main part, thus "cutting" our last ties to the old stuff. Which would allow us to enter Meracydia, The New World, etc without any old plot hooks or old "we're falling back on this predictable enemy faction" decisions coming into play.
