A skill in astronomy allows the character to chart the stars and planets. This skill is quite useful in ship navigation at night, or by traveling at night on land without a map. Aside from granting the character knowledge of stars and other stellar objects, it also doubles as Direction Sense and Navigation (but only at night). This skill can also help the character understand certain occult events that deal with the placement of planets and stars.
Critical Success: The character navigates as intended and knocks a day off the travel time, if possible.
Critical Failure: For whatever reason, the character just can’t figure out his current location or the location of his destination that night.
