This series of tables were originally going to be used with The Warrens random encounter table, as I wanted to emphasize the both the accretion of large amounts of time and the hostile/unnerving nature of the place.
Section 1 - Interaction w/Ghost(s)
The ghost(s) involved in this haunting are unaware of the activities of the living and in fact cannot be interacted with. Generally they are re-enacting something, either a daily routine or whatever happened before their (probably untimely) demise. Go to Section 2.
3-6 Aware, Communicative
These ghosts are aware of the living, although they cannot interact physically with them. They can communicate with the living, although the method involved varies. Go to Section 3.
7-10 Aware, Interactive
This category covers ghosts who are aware of the living and can interact with them, this can mean attacking them although given how powerful ghosts can be, this is inadvisable if it can be avoided. Go to Section 3.
Section 2 - Unaware Ghosts
1-3 Single Entity
The lone unaware entity is typically a soul that's forgotten or hasn't realized that they're dead. They are usually seen going through some sort of daily activity or routine, even if the architecture around them has changed.
4-9 Multiple Entities (2-4)
Multiple ghosts encountered at the same time, reenacting a death of one of the entities -- betrayals, assassinations of important figures and similar situations tend to create these hauntings.
10 Tableau (8-18)
This rare situation involves a multitude of ghosts, almost always reenacting a scene of incredible violence or tragedy. The tableau generally appears on the anniversary or at the time of day that the
original event occurred.
The ghost(s) are some level of transparent, usually with a slight glowing effect.
The ghost(s) will appear to be fully material, although any attempts to interact with them physically will involve objects/limbs going through them. If somebody puts their limb inside a ghost, they will experience a cold numbness and a feeling of dread. If they persist, they must make a save against Spells/Will Save to avoid being possessed by the ghost in question. The ghost may not initiate contact and must allow the player to withdraw.
Section 3 - Aware Ghosts
1. For whatever reason, I feel like these should be solitary encounters. Change if you want!
These ghosts have no physical form, at least not visible. Mayhap they can be seen on the Ethereal Plane.
10 Fully Corporeal
Appears to be a regular person until touched -- rules for possession are the same as above.
This ghost can't communicate except for acting things out, pointing at things, etc. If you rolled Invisible above, congratulations, you got yourself a Poltergeist, who will communicate by knocking things over, throwing things at the players, writing creepy messages on walls, etc.
Ghost will give dire warnings, spout obscure forecasts, complain about lack of respect, deride fashion choices, etc.
Roll yr standard reaction and/or roleplay out the encounter, here's a little table to make the latter a little easier:
6-7 Deliver a Message (Tell Hossfoss that the family silver is underneath the fireplace)
8-9 Set Things Right (I couldn't do this, now you can do it for me)
Example Ghost: Aware, Interactive Ghost - Translucent, Communicates through Charades, Wants to Set Things Right -- The combination of the latter two aspects should make for an entertaining encounter, especially if the ghost wants to do something sufficiently abstract, like interfere with the succession for a minor title...
