Astrology
Astrology is a real force in the iVerse (as opposed to the pseudoscience it is perceived as in modern times). It is a divinatory/revelatory practice that can reveal some small Sign or Oracles denoting either positive or negative outcome under specific circumstances. It is usually practiced as a Ritual.
Though most practitioners of who call themselves astrologers are charlatans preying upon the weak, the true cosmological Pattern delvers seek to reveal Portents by mystic sight and travel. They are trained to recognize markers and weaves within The Pattern in order to reveal the significance and probability of future events. These can seek out auspicious moments (favorable to them or least favorable to opponents) to attempt tasks, pathways to truth and knowledge, and even insights into journey-taking. The act of Astrological Delving catalyzes the weave around the target – making the likelihood of their vision nearly certain (though details leading to and away from the vision are open) – it would take a strong Essence to impose a change to The Pattern to change the delving outcome. A delving can be done on any moment which is greater than an hour in the future. The delver loses 1 essence until the moment has passed or is no longer relevant, and makes a fated skill check. A Reveal check will reveal randomly what the portents will be. A Seeking check attempts to find the best moment: full = A Favorable Encounter (the entire moment); major = A Favorable Instant (the initial round of the moment); average = A Rancorous Instant (the initial round of the moment); simple = A Rancorous Encounter (the entire moment); failure – unclear, no further checks.
Frame of Reference: All Skills are bound by the character's Setting (physics), and the details that their culture/society's Science (gathered by Technology), direct experience, and/or collective Records are capable of revealing. A character may not be able to apply their full measure on a different world, with different species and tools.
