According to the official description:
"At the close of the Age of Fire, as the world ends and all lands converge upon themselves, a lone adventurer descends into the madness of the earth and uncovers the secrets of the past. As players make their way to the fabled Ringed City they will encounter ancient beasts, a new cast of characters teetering on the edge of insanity, new armor, weapons, magic, and at the bottom of it all, a long lost city filled with new horrors for players to overcome."
The Ringed City looks like we'll finally get to see the city of hollows itself, Londor. It also makes me wonder, was that tall woman with the crumbling jar thing Velka? Regardless, I'm super excited for this last installment, and looking forward to what other games FromSoft will move towards after this. Though, I do hope this last DLC will offer us answers to questions from long ago, as well as point to the future. Maybe the end of the age of fire means their new dark fantasy game will be from the age of water Aldrich dreamed of.
As much as I liked Ashes of Ariandel, I have to truly hope that they can match the scope of Bloodborne's Old Hunters DLC which was unbelievably well thought out and executed.
Dark Souls 3: The Ringed City arrives on March 28th for $14.99.
(Or as part of the DLC Season Pass for $24.99)
