That spell list contains a number of spells.
Intuitions -- these show visions of what would happen based on a specific action. The thing to remember here is that further from that specific action you get, the more alternatives will be available. For example, take Inuitions III, the action is "opening that door". The vision will show opening the door, seeing the orcs on the other side, the orcs seeing you, and the onset of melee, and then the visions will start fragmenting, showing PC A defeating an orc, and then being defeated by the same orc, showing the party winning, showing them losing, etc.. The future is always in motion.....
Now, the players will then likely setup and prepare for opening the door once a player has seen that -- keep track of time!!! -- because they didn't open the door immediately, things will change. The orcs may have left the room, more may have joined them, they may have heard the PCs on the other side of the door preparing (and thus begin preparing themselves, etc...
The thing to remember is that everything is always in motion, and always changing, so unless an Intuitions is acted upon immediately, the future shown will change.
Dreams -- These spells give the caster a dream about a specific topic. However, dreams are mostly symbolic in nature, and thus must be interpreted. They will not give straight answers to specific topics. Nothing will be straight forward, the dreamer must figure out the dreams given.
Death's Tale -- This and the Death's Tale True are often the ones folks find the most problematic for GMs. The thing many folks forget is that these are visions, as such, they are pulling images from the past. This means that the images will be from the key points in the chain of events leading to the death.
For the 6th level spell, the vision is from the viewpoint of the dead character. And the image of killer will be an image of him at the time he caused the death. If the killer were in disguise, you would see him in the disguise, not in his normal form.
The same applies for Death's Tale True -- if the killer were in disguise, you would get images of him in disguise, not in his true form.
DTT says "understanding of the reason(s) the deceased died". This means the cause of death, not the motivations behind it. If it were a heart attack, you would get a vision that gives that. If it were poison, you would get a vision that indicates that, perhaps even with enough detail that a little research could let you identify the poison.
"exactly who the killer was" -- again, this is the person that was directly responsible for the death, the one who gave the poison, or put the poison in the deceased's food, the one who stabbed him, etc... Again, it shows the killer when performing the action that causes the death, so disguises would be shown if worn.
"who was ultimately responsible (if any)" -- This could be the same as the killer, or it could be some noble who idly wished, in the presence of underlings, that the deceased was no long a thorn in his side, and whose underling took that idle wish and then acted upon it in a manner in which the noble didn't actually mean. Or it could be somebody who actively wanted the deceased dead and who hired the killer. Or the death could be an accident (oops, the visitor dropped the soap on the way back to his chamber from the bathing room, and the prince stepped on it and fell down the stairs and broke his neck -- the visitor is responsible, but it was still an accident (no killer!))
However, as with the killer, the vision will show the image of this person (if there is such a person) at the time that they initiated the sequence of events that led to the death. So if the person is in disguise, it will show the disguise.
These spells should NOT be treated as all powerful. They can only show what existed at those moments.
As for the Communal Ways spell list, it is a Cleric Base List, this means that there needs to be a Cleric capable of casting those spells. If there is no Cleric, or no trusted cleric (as only the cleric sees the visions, and he can always lie...), then there will be nobody to cast these spells.
Conversely, if these spells are common, then there WILL be counter-measures to protect against them. Devices that blur the character's images in scrying spells, or that block them altogether, etc..
