Fenrir and Sarah sends you back to the past inside Glast Heim castle to witness (and survive) a legendary duel between the Valkyrie Fenrir and the sorceress Sarah Irene. The instance has no fixed time limit but is mechanically demanding. The main reward is Fragments of Gigantes, which are used to enchant Sarah's earrings.
💡This is a 3rd-class endgame instance. You need Base Level 145 to enter. Party leader creates the instance via Professor Bernhard in Dali02. Completing the Isle of Bios instance first is strongly recommended since both are part of the same quest chain (ep14 arc).

Talk to Professor Bernhard in Dali02 to unlock the instance.
Professor Bernhard is a weapons researcher who wants you to retrieve Gigantes shards from the past. Talk to him as party leader to get the quest started, then create the instance.
After his dialogue the Dimensional Device near him becomes active for your party.
Enter the instance and advance through the Mutant Galion waves.
You spawn inside a past version of Glast Heim castle. Vrid and Zeith (two companions from the Isle of Bios arc) are with you. The first enemies are Mutant Galions scattered across the castle corridors.
| Enemy | Level | Notes |
|---|---|---|
| Mutant Galion | 150 | Groups of 3-6 per corridor; sturdy |
| Wicked Mutant Dragon | 150 | Appears in later waves; hits hard |
| Wicked Chimera | 150 | Mixed in with dragons |
Clear each area before Fenrir's dialogue advances the script to the next zone.
Reach the throne area and kill the Gigantes escorts.
The duel between Fenrir and Sarah begins deep in the castle. Before the main boss spawns, two Gigantes variants appear as escort enemies guarding Sarah.
| Enemy | Level | Notes |
|---|---|---|
| Gigantes | 160 | Small variant; fast |
| Gigantes | 160 | Slightly larger; more HP |
| Large Gigantes | 160 | Spawns in pairs during the boss fight; interrupt these quickly |
Kill all Gigantes before engaging Sarah Irene directly.
Fight Sarah Irene in the throne chamber.
Sarah Irene is the final boss. She is a magic-heavy sorceress who periodically re-summons two Large Gigantes bodyguards. Prioritize killing the bodyguards when they appear, then resume attacking Sarah.
| Boss | Level | Notes |
|---|---|---|
| Sarah Irene | 160 | 100 million HP; re-summons Large Gigantes twice during the fight; spreads AoE magic |
The fight ends when Sarah's HP drops to zero. A final story scene plays.
Collect Fragments of Gigantes and use them to enchant Sarah's earrings.
After the fight, Vrid gives you a reward. The main valuable drops from the Gigantes enemies throughout the instance are Fragments of Gigantes, used at Professor Bernhard to enchant the Sarah's earrings accessories.
Fragments Of Gigan -- crafting material for Sarah's earring enchantsSarah's Left Earring -- one of two earring slots; awarded on first completion (choice of left or right)Sarah's Right Earring -- second earring slotNotes
- Enchanting earrings. Talk to Professor Bernhard outside the instance to enchant Sarah's earrings. Each attempt costs 4 Fragments of Gigantes. Enchanting can fail and destroy the earring -- initialize the enchant slot first (1 Fragment) to reduce risk.
- Gigantes drop Fragments. The Small and Large Gigantes drop Fragments throughout the run. You get more per run by killing all of them, not just during the boss phase.
- Level 145 hard gate. Below 145 Professor Bernhard will not talk to you at all.
