No the devs said there is no sixth keystone. They are currently in development of the final boss fight for people with all 5 keystones (pretty much all the veterans), and will release it in a future update, whenever thats gonna be. It might be at the end of the year as part of a weird new winterfest thing, but that's just my idea. The dude at the island says the real battle begins later this year, which would assumingly be in December as part of a Winterfest twist since its already November.
