The Return of the Ancients expansion has introduced some of the most exciting endgame content ever seen in Path of Exile 2. Among the new features, the Keepers of the Flame questline stands out as one of the most important progression systems in Patch 0.5. Not only does it introduce players to the Hiveborn threat, but it also unlocks the Genesis Tree, Breach progression, powerful crafting options, and some of the expansion's biggest boss fights.

If you are wondering how to start the Keepers of the Flame questline, where to find Ailith, how to complete Breach encounters, or how to defeat Xesht, We That Are One, this complete Path of Exile 2 Return of the Ancients Keepers of the Flame quest guide will walk you through every step.

As someone who has already spent dozens of hours pushing through the new Breach content, I can safely say this questline is one of the best additions to Path of Exile 2's endgame.

What Is the Keepers of the Flame Questline?

The Keepers of the Flame questline is the primary storyline connected to the new Breach mechanic introduced in Return of the Ancients.

Throughout the quest, players work alongside Ailith, a member of the Keepers of the Flame, to stop the Hiveborn invasion spreading across the Atlas.

Completing the questline rewards players with:

Genesis Tree access

Breach progression systems

Hiveblood crafting resources

Wombgift cultivation

Breach Passive Points

Access to advanced Breach encounters

Exclusive endgame rewards

Because of these rewards, every endgame player should prioritize completing this questline as early as possible.

How to Start Keepers of the Flame

The first step is finding your initial Breach encounter.

Meet Ailith

Many players first encounter Ailith during Act 6, particularly around the Mud Flats region.

However, the full questline officially begins after completing a Breach encounter within the Atlas.

Find a Breach

Breach encounters appear in two ways:

Random Atlas maps

Atlas waypoints marked with a purple flame icon

Once you enter the Breach and stabilize it successfully, Ailith will appear and explain the growing Hiveborn threat.

She then unlocks the path leading south toward the Monastery of the Keepers.

Travel to the Monastery of the Keepers

After your first successful Breach, follow the newly unlocked route on the Atlas.

Once inside the Monastery, speak with Ailith to continue the storyline.

This area acts as the central hub for all Keepers of the Flame progression.

Here, you will learn about:

The Hiveborn

The Keepers of the Flame

The Genesis Tree

Advanced Breach encounters

Future quest objectives

Unlocking the Genesis Tree

One of the most valuable rewards from the questline is access to the Genesis Tree.

How the Genesis Tree Works

The Genesis Tree is a unique crafting and progression system powered by Hiveblood.

Ailith will provide a Lavish Wombgift and ask you to place it into the Currency Womb.

Doing so unlocks the Genesis Tree's crafting pathways.

The system allows players to cultivate powerful rewards including:

Rings

Amulets

Belts

Currency

Breachstones

Specialized crafting materials

The Genesis Tree becomes increasingly important as you progress through Return of the Ancients.

Stabilize and Collapse Breaches

After unlocking the Genesis Tree, your next major objective is stabilizing and collapsing Breaches.

How Breaches Work

Breaches function similarly to expanding combat zones.

Hiveborn enemies continuously emerge from the breach.

To stabilize it:

Defeat enemies quickly

Keep the Breach open

Fill the progression meter

Avoid losing momentum

Once stabilized, elite Hiveborn enemies will appear.

Defeating these elites causes the Breach to collapse and rewards valuable loot.

Breach Farming Tips

As a veteran player, I strongly recommend focusing on clear speed.

The faster you kill enemies, the easier it becomes to maximize Breach rewards.

Strong area-of-effect builds perform exceptionally well during these encounters.

Collapse Five Breaches

To advance the storyline, you must successfully collapse five Breaches.

Fortunately, previous completions count toward the objective.

After reaching five completed Breaches:

Return to Ailith

Speak with her at the Monastery

Unlock access to the Hive Colony

Receive additional quest progression

This marks the beginning of the more difficult portion of the questline.

Complete Breach Fortresses

Before reaching the Hive Colony, players encounter Breach Fortresses.

These are some of the most memorable encounters in Return of the Ancients.

Defend Ailith

Inside each Fortress, Ailith actively participates in combat.

Your goal is simple:

Keep Ailith alive.

Wave after wave of Hiveborn enemies will attack.

If Ailith dies, the encounter fails.

Use Environmental Tools

Several temporary abilities appear during the defense.

These may include:

Healing effects

Protective barriers

Area damage abilities

Defensive buffs

Using these tools effectively can dramatically increase your chances of success.

Escape the Fortress

After surviving the defense phase, the Fortress enters a collapse sequence.

The structure transforms into a maze.

Exits begin sealing.

Wrong routes become blocked.

You must quickly navigate back to the entrance before becoming trapped.

Many players fail this stage because they focus too heavily on fighting instead of escaping.

Enter the Hive Colony

Once the Fortress is complete, follow the Atlas route into the Hive Colony.

This area serves as the heart of the Hiveborn infestation.

Fight your way through:

Hiveborn swarms

Elite enemies

Dangerous environmental hazards

Mini-boss encounters

Eventually, you will reach the Nest of the Lords.

Defeat It That Was Tul and It That Was Esh

The Nest of the Lords contains one of the most challenging encounters in the questline.

Understanding the Boss Fight

You must fight:

It That Was Tul

It That Was Esh

Initially, the bosses alternate combat phases.

Later, they fight together.

During the final phase:

Both share a health pool.

Damage to one damages both.

Positioning becomes critical.

Tul's Abilities

Tul specializes in:

Physical damage

Cold attacks

Shield slams

Area control mechanics

Esh's Abilities

Esh focuses on:

Lightning damage

Chaos effects

Projectile attacks

Dangerous ground zones

Defeating both bosses rewards:

Hiveblood

Wombgifts

Breach-exclusive uniques

Breachlord Bloodline rewards

Unlock the Twisted Domain

After defeating Tul and Esh, you will receive the Breachlord Sac.

Return to the Monastery and locate the Mysterious Acolyte.

Give the Breachlord Sac to the Dreamer.

Once awakened, the Dreamer grants access to the Twisted Domain.

This area contains the final challenge of the Keepers of the Flame questline.

Fight Alongside Ailith

The Twisted Domain introduces a timed assault encounter.

Ailith joins you once again.

Managing the Timer

A countdown begins immediately.

Defeating elite Hiveborn enemies extends the timer.

To succeed:

Keep moving forward

Focus elites first

Avoid unnecessary backtracking

Use mobility skills aggressively

Failure to reach the checkpoint before time expires results in failure.

Defeat Xesht, We That Are One

At the end of the Twisted Domain awaits Xesht, We That Are One.

This is the final boss of the Keepers of the Flame storyline.

Boss Strategy

Xesht combines:

Massive area attacks

Hiveborn summons

Movement restrictions

Heavy damage bursts

The fight demands strong positioning and situational awareness.

Save your strongest defensive abilities for large attack sequences.

Many players underestimate the amount of movement required during this encounter.

Find Ailith After the Final Battle

One of the most common issues players encounter involves locating Ailith after defeating Xesht.

Where Is Ailith?

Return to the Monastery of the Keepers.

Many players expect her quest marker to appear normally.

Instead:

Walk past the Genesis Tree.

Head toward the far left side of the Temple.

Continue into the hidden alcove.

Ailith is waiting there.

Speak to her to officially complete the Keepers of the Flame questline.

Keepers of the Flame Rewards

Completing the questline unlocks several major endgame systems.

Rewards include:

Genesis Tree access

Full Breach progression

Hiveblood crafting

Wombgift cultivation

Twisted Domain access

Advanced Breach farming

Six Breach Passive Points

These rewards make the questline one of the most valuable pieces of content in Return of the Ancients.

Many players also farm additional Breach content afterward to acquire valuable Path of Exile 2 currency and optimize their endgame builds. Some players use G4mmo as one of the available marketplaces when researching trading options and game resources.

Final Thoughts

The Path of Exile 2 Return of the Ancients Keepers of the Flame questline is much more than a simple story chain. It serves as the gateway to Breach progression, the Genesis Tree crafting system, Hiveblood farming, and several of the expansion's most rewarding encounters.

From defending Ailith during Breach Fortresses to battling Tul, Esh, and finally Xesht, every step introduces new mechanics that prepare players for the increasingly difficult endgame content of Patch 0.5.

If you are diving into Return of the Ancients for the first time, completing Keepers of the Flame should be one of your highest priorities.
