If you've found the cave, then that's all for version 1.10 content on the new continent (though you still might find some content on the "old" continent since there is much more there).
There will be more content on the new continent with in version 1.11 that will be released here in 8/9 days :D (it is currently only available for people having early accesses), including scenes with the companion you might have found in the cave
