If the rule “Thereputic Isolation” exists, add the following text to it:

Once per dynasty, each Student may declare themselves On Vacation by making a post to the blog with the word “vacation” in its title.  This post must also specify a duration of real-world time of at least 48 hours.

While a Student is On Vacation, e may often halve eir Sanity, if it is less than -1, or add 1 to it if it is between -1 and 5.  E may not take any action which is allowed by a Dynastic Rule besides this one, unless a Dynastic Rule specifically requires em to.

After the specified time has elapsed, e is no longer On Vacation.
