All players choose one of their personal curve tiles and hold this tile up in such a way that it
is clear to see in which direction the curve shall be executed (always touch the curve that you
choose at the end that will be placed at your magic book).
All players put their selected curve at their magic book exactly in the same way the curve was
A player who intents to fly instead of placing another curve simply points his index finger in the
air - thus not selecting a curve. Please intone a humming noise when doing this - just for the fun of it.
Whenever several players decide to execute their flight the castles are used to determine the
exact order in which these flights are executed - going from the lowest numbered up to the highest
After all players have executed their flights these players (only) give their personal castle to
the next player in clockwise order who also did execute a flight this turn.
With other words: only the flying players exchange their castles.
A player who selected a curve will keep his castle. This is also true for a player if this player was
the only one to execute a flight in a turn.
All players executing a flight take back their curves.
