The subtitle has long been painted on the key art’s ribbon, and now it is part of the name: Ancient Warriors: Order of the Seal. The order that sealed the crypt under Riverhollow’s old cemetery is the thread of the story, and the seal the hero one day takes from the Necromancer’s neck is its knot.
Your saves do not depend on the name: the folder your heroes live in, the app’s identifier and the cloud snapshots are unchanged, so nobody loses anything.
