Who: Selester, Alyana, and anyone who intercepts the note (likely a few Maesters and probably the Master of Whispers).
What: A raven is sent from Summerhall by the Tyrell Maester, carrying a note addressed to Lady Alyana Baratheon.
When: The note leaves on the 18th; I believe it's a 1-day travel time for ravens?
Status: Presumably relatively closed communications.
Rating: PG. Unless someone decides to write naughty letters. Though, really, that would just scandalize a bunch of poor Maesters.
