From the moment you take control, the goal is to work across the burning Paris streets and down into the sewers to confront The Fallen. The path runs through a chain of areas, pauses at a save point partway down, and reaches The Fallen before the Arcane Whip is unlocked in a later conversation.
Quick answer: Head right from the start through the Bank of the River Seine, Undercity, and Ruined Market, drop into the Central Sewer Drain to save, then descend through the Sewer Reservoir and Path of the Rat to the gate chamber where The Fallen waits.
Route through Paris Streets to the gate chamber
After the opening, a banner sets your objective: “Investigate the streets of Paris”. The areas appear in this order, so follow them straight through.
"Press [Square] to attack."
"Press [Triangle] to cast a spell. Spells require Mana to cast. Recover Mana by attacking enemies." Later prompts cover a longer jump, clinging to walls, and the slide, "Press [left stick] + [Circle] to slide...", along with a heal prompt for using a potion."Press [Circle] while stationary to perform a backward dodge. Pressing [Circle] again during the first dodge will cause you to move even further back.""This mirror saves your progress, you heal yourself completely and fill your potions. Upon use, roaming monsters will reappear. If you die, you will resume your adventure at the last mirror you interacted with."
"Placing a MARKER on a secret or an unreachable location allows you to return to it later." Pull the ground lever to work the gates."Work of Mercy completed" pop-up. Keep descending; a second spirit offers another hint about the monster.Join readers who trust AllThings.How

The fight begins with a single red health bar labeled THE FALLEN. Bring it down to empty to clear the encounter. For every attack and how to dodge it, see how to beat The Fallen.

After the final hit, an Absorption phase starts. Hold the prompt shown as "During the Absorption phase, hold down [R1] to absorb the power of the Arcana." This grants the tarot card The Fallen, which carries the Holy Cross spell.
You also receive The Fallen’s Key, described as "One of three keys needed to open the sealed door to the Catacombs. Obtained by defeating The Fallen."

A tutorial then explains how Arcanas work: "Absorbing and equipping an Arcana allows you to use its powers in combat. Each Arcana has a unique spell. Open the Equipment menu, then select the currently equipped Arcana to replace it with another spell available in the Arcanas collection."
Unlock the sealed gate with the key. A banner displays the updated objective, beginning “Unlock the gate to the Cata…” (the gate to the Catacombs). You still need two keys; continue into the sewer tunnels on the right.
Unlocking the Arcane Whip
Travel through the tunnels for a short while to trigger the Arcane Whip introduction: "Arcane Whip. Aim with [right stick] then press [R2] to hook onto Luminous Anchors or Enemies and reach new areas."
Follow-up prompts cover each use of the whip:
"Aim at a round anchor with [right stick] and hold [R2] to grab onto it and swing like a pendulum.""You can now grab onto sharpened anchors to get closer to them and reach other platforms. Aim at the anchor with [right stick] then press [R2] to propel yourself towards it.""Keeping [R2] pressed when using the whip will increase the pendulum's duration to reach higher platforms."
With the whip, aim with the right stick and hold R2 to swing like a pendulum.
