It's hero vs hero in Heart of Stone: the first quest in RuneScape's new 'Elder Gods' series, and your choice from the Player Power quest poll earlier this year.
Legendary hero Xenia has gone rogue, and Ariane's vowed to take her down. You'll team up with a state-of-the-art tracking golem - whose personality will develop based on your choices.
Ultimately, you'll find out what drove Xenia to murder, and uncover a secret that could change Gielinor forever.
There's Thanksgiving fun to be had from Thursday, too, as the Lumbridge Castle chef's brother needs your help to find his wayward turkeys - there's a new title to earn for doing so.
When the quest starts, you'll find Xenia and Ariane in a heated disagreement.
Once Xenia flees the scene, Ariane will kit you out with a tracking golem named Kipple. You'll need to tune into to the magical teleportation traces left by Xenia, and follow her trail around the world.
You'll visit a number of locations, completing puzzles or battling guardians at each one, uncovering long-lost secrets of the elder gods as you do so.
Succeed in tracking down Xenia and you'll earn a chunk of XP, plus a golem follower pet, whose personality will be defined by the choices you made during the quest.
You'll also have set in motion the events of an all-new quest line - one that'll be right at the core of RuneScape's Sixth Age.
The Lumbridge Castle cook's brother has unwittingly unleashed a flock of turkeys, and it's up to you to find them up in our Thanksgiving event, running from 00:00 GMT on 27th November to 23:59 on 30th November.
There are 20 to locate all around Gielinor - 10 in free-to-play areas, and 10 only accessible to members.
Find 10 turkeys and you'll unlock the new 'the Thanksgiver' title, plus all free-to-play rewards from Thanksgivings past.
Track down all 20 and you'll get a large XP lamp, plus all previous members' Thanksgiving rewards.
You can also join Mod Jon and Mod Neena for the RuneScape Thanksgiving Parade: 16:00 GMT on 27th November at Varrock Square on World 34. Visit the events forum thread for details of this and other fun in-game events.
