The Sword of Roele is detailed in the adventure of the same name its
powers are rather slight to be honest. Th e "Crown of Haelyn" is a
constillation in the sky over cerilla. The State Crown and the Imperial
crown of Anuire as somehat detailed in the Book of Magecraft, thier
power game from the bloodstones with which the were adorned. The
adventure "Sword and Crown" deals with a periodic gathering of the
Regents of Anuire in which the host Rengent is given a replica "Sword
and Crown" to act as the chairman of the event and act as arbitrature of
some matters. Though it seem to me that most regents would ignore
things they don't like anyway.

Hope this helps,
Kyle
