That is a very good point, actually. Although the Void already has diminished barriers, hence the fact that it's possible for minor Voidsent to pass between the worlds in some cases, if the barriers were of her creation, and they were to fray, it could mean even more powerful Voidsent could readily pass between the worlds as opposed to requiring a voidgate, amongst other things. They did seed a storyline for its potential rehabilitation into the final quest for the role quests for SHB, so a future visit there is likely. There would be the small matter of the RPR avatar but I am sure that can be dealt with rather easily...
