Aspects

See main Numina page for summary of aspect mechanics

Time Period	Accuracy	Question
One week	Incredibly vague at best	A very simple question (can be answered with Yes or No... but don't expect to get that simple an answer!).
One month	Generally accurate, but deeply cloaked in symbolism	A specific question that can be answered quickly: "Is this bridge safe?" is okay. "How are the bad guys going to attack us?" is not.
One year	Accurate, but not always explicit	A query that is somewhat detailed but could be answered using publically available knowledge, if you knew where and how to look and had the time.
10 years	While still cloaked in symbolism, the truth is in there, and digging it out shouldn't be too hard	A detailed question that requires information or details that have been hidden by time, distance or deliberate obfuscation but can still be unearthed with effort.
20 years forward, up to 100 years backward	Your results are almost always accurate and usually easy to understand	A very detailed question or one that would need access to information that has been lost to time, is very distant or has been actively guarded and hidden.
Almost unlimited, in either direction	You know what will happen, when it will happen and who it will happen to, without question... unless you're wrong, of course	No question is too complex, no information too obscure.
