The NPCs on this list are considered "Essential" by the game. If any of them are killed at any time, you will receive a message stating:
With this character's death, the thread of prophecy is severed. Restore a saved game to restore the weave of fate, or persist in the doomed world you have created. |
This means that you will be unable to complete the Main Quest. A list of essential NPCs in Morrowind can be found here.
| NPC | Location | When Essential |
|---|---|---|
| Captain Falx Carius | Fort Frostmoth, Carius' Chambers | |
| Tharsten Heart-Fang | Skaal Village, The Greathall / Solstheim, Mortrag Glacier: Inner Ring |
