OOC:
Here is a GM suggested roll to determine Moonshadow's next move (I modified the idea a bit):
On a 1...the bird falls back into 'self preservation' mode and flies out of the castle.
On a 2-4, his love and concern for his master dominates and he heads back to where he left Kendral (the source of the explosion).
On a 5 or 6 Moonshadow understood the gist of Kendral's intentions with the note and leads Xaka's party to the skiff. He assumes the explosion is Kendral and Grimbly taking care of business.
