Gifts of the Tide Queen

The Nine Gifts of the Tide Queen are a set of nine magical items of great power, entrusted to the Matriarchs of the High Houses by Erastes Tideborn herself.
All nine gifts are said to be of significant ceremonial and magical importance; whilst the precise details are unclear, it has been claimed that it is absolutely essential that all nine of the Gifts are present for a ceremony which occurs annually in Ysberinge on the third night of the Festival of Hrenisha, which takes place on the first new moon after the winter solstice. The effect of the gifts not being present are unknown, but have been implied to be catastrophic - theories include that it may result in the metaphysical basis of the crown of Aldernord being vulnerable to usurption by some entity, or event that it could cut off the Daughters of Null from their descendants.
The Nine Gifts are:

• The Clawed Rod - held by House Bheuren
• The Ivory Sceptre - held by House Canthor
• The Sword of the Tides - held by House Erastes
• The Shield of the Drake - held by House Mettvergen
• The Sash of Valour - held by House Riddacci
• The Whispering Knife - held by House Sarren
• The Mantle of the Inexorable - held by House Votellian
• The Armour of the Unconquered - held by House Ysern
• The Ring of Winds - held by House Zaal
