Revision 1

Overview

Serpent Marsh is an island located to the south of the Demeniss region in Pywel. This marshy, waterlogged area is significant as the home of Lyselia, the Witch of Humility, who resides in a hidden cave on the island. Players visit Serpent Marsh as part of their journey to locate the witches of Pywel and gain access to Abyss Core services.

Location

Serpent Marsh is situated south of the Demeniss mainland. The island features a teleporter (Abyss Nexus) relatively close to Lyselia's cave, making return visits straightforward once the area has been initially discovered. Players will naturally visit this area during Chapter 9 of the main story.

The Witch Lyselia

Lyselia, the Witch of Humility, is one of several witches scattered across Pywel. Like other witches, she provides Abyss Core and Abyss Gear services, allowing players to extract, embed, and create cores. Her cave entrance is located between two mountains, close to an Abyss Nexus. Colorful flags inside the cave mark the path leading to Lyselia.

How to Reach

To reach Lyselia's cave, travel to the southern part of Demeniss and cross to Serpent Marsh island. Look for the cave entrance between two mountains near an Abyss Nexus. Follow the colorful flags inside the cave to find Lyselia. This area becomes accessible during Chapter 9 of the main storyline.

Hidden Weapon: Eastern Witch's Fan

Serpent Marsh also contains a hidden weapon called the Eastern Witch's Fan. This weapon is tucked away behind a destructible barrier in a narrow canyon on the island, making it easy to overlook during a normal visit to Lyselia's cave.

How to Find

To obtain the Eastern Witch's Fan, look for a narrow canyon gap on Serpent Marsh. You need to fly through this gap (using a glider or aerial traversal). Once through, you will encounter a bismuth wall blocking a small alcove. A glowing orb is positioned near the wall. Hit this orb with Axiom Force to shatter the bismuth barrier. The Eastern Witch's Fan is inside the alcove behind the destroyed wall.

This is one of several hidden weapons scattered across Pywel's locations that require players to interact with environmental puzzles rather than defeat enemies. Keep an eye out for glowing orbs near bismuth walls in other areas as well, since these destructible barriers often conceal valuable loot.

Nearby Locations

• Demeniss : The main region to the north of Serpent Marsh

• Reventine Monastery : A notable location in the Demeniss region

Tips

• Tag the Abyss Nexus near Lyselia's cave immediately upon arrival. This saves considerable travel time for future visits.

• If you are visiting before Chapter 9, you may not be able to access all of Lyselia's services. The full unlock happens as part of the main story progression.

• Look for the colorful flags inside the cave to navigate to Lyselia. The cave entrance is easy to miss between the two mountains.
