Overview

The second instance related to the Episode 14.3 which you can access after clearing Bios Island once.

In this instance, you and and your party are teleported from one small room to another and flooded with waves of undead monsters, until eventually confronting Mors.
While mechanically simple, this instance requires an organized group that balances its survivability and damage output very well, as it's rather easy to get swarmed by the waves of undead.
The layout also makes positioning very important since there isn't much room to navigate.

Background and Lore

Ankou is up to no good once again. This time the action takes place in a dreamlike world that's a reflection of a real location, the secret underground complex where Mors perfected his dominion over the art of necromancy. This time you don't get to confront Ankou directly but instead face the endless waves of undead and other illusions he has created.
At the end, Ankou raises Mors to stop your group.
Nothing is known about Mors, but the architecture of the place indicates that his history may very well go back to the time when Ymir was still whole.
As you dispatch the undead minions of Ankou, you begin to realize that you're being toyed with and all your efforts are only speeding up the resurrection of Morroc...

Inside you also meet an old acquaintance and member of the expedition that helps you out by distracting Ankou. Eventually getting caught, his soul separated from his body and later used to bring back Mors. Surprisingly, your companion doesn't perish but instead weakens Mors before continuing his chase of Morroc. The rules of this place make no sense at all.

Tips

The fight against Mors is divided into two phases, first you face his spirit form, Warlock Mors, a ghost property spellcaster.
While slow, he dishes out large amounts of spell damage without rest and applies nasty debuffs.
It's a good idea to watch out for the Stone Curse + Crimson Rock and Jack Frost + Varetyr Spear combos and remove the statuses before the next spell goes out.
There are no undead monsters being summoned during this phase but the group will get hit by area spells from time to time so don't slack.

Once defeated, Mors will assume his real form, Necromancer Mors, an undead spellcaster that shields itself with walls of minions.
From this description alone, you should know what to expect; endless waves of undead monsters, area spells and nasty debuffs.
This encounter is an aggravated version of what you experienced beforehand, and while you can potentially get rid of Mors quickly, so can he eliminate your group.
Your group must balance the killing of undead minions with damaging Mors while staying alive.
If things look grim and you're getting swarmed, it's a good idea to stop provoking Mors with attacks while clearing out the minions and replenishing the group.
