Does the cave contain more powerful necromancy beyond the gate? Or is it simply a coincidence that the Elder Seer greets Death students in this same clearing?
Or could it lead to Sunken City or Nightside where the Death school ended up after Malistaire caused it to disappear from it's former location with the other Ravenwood schools.
Why would they be connected? Well, the Elder Seer appears outside the gate in the Haunted Cave, but the Elder Seer is also connected to Nightside and is known by Mortis.
Additionally, by looking at the map it appears that the Haunted Cave leads in the direction towards Nightside. Similar to how the Dark Cave connects Cyclops Lane and Firecat Alley across separate tiers of Wizard City, possibly the mysterious Death gate in the Haunted Cave does the same thing between Triton Avenue and Nightside.
That is just one theory. Leave a comment and share more!
