His escapade begins as he plans a simple flight on board his dragon, Spit Fyre, to retrieve his friends from the Trading Post.

Due to an unfortunate mix-up, the SafeCharm falls into the hands of Merrin Meredith who stole it believing it to be a rare perfume.

Jenna, getting tired of Milo's hospitality decides to leave the ship and fly off home with Septimus and Beetle on Spit Fyre.

They try to find the Cattrokk Light, a lighthouse in the middle of the ocean, and fall onto a nearby island when Spit Fyre's tail gets struck by lightning.

Syrah heals Spit Fyre's tail and reveals that she is under a terrible enchantment by the resident evil ghost of the island known as Syren.

The Syren, a singing ghost who attracts sailors by her voice and leads them to their doom by possessing them, stays in a tower atop the hills of the island.

Syrah takes Septimus there to show him an opened ice-tunnel latch beneath the island; she mentions that danger is approaching the Castle.

Meanwhile, Marcia goes to the Manuscriptorium vaults and finds that the ice tunnel latches, which pass from The Castle to the Seven Isles of Syren, through Cattrokk Light to the House of Foryx, are opened.

Suspecting that the evil ghost Tertius Fume may be behind this, she returns to the Wizard Tower to find Zelda who informs Marcia about Septimus' danger.

The ship's captain and his henchmen take the light from the lighthouse and transport it to the island where Jenna and Beetle reside, and they see them coming.

To their horror, Septimus and the others find that the jinnie warriors come on board and address Tertius Fume as their master; he is on the island directing them towards the Syren tower ice tunnel.

Septimus and Beetle come to the conclusion that since Jim Knee was in a golden bottle, he has the power to overcome the warrior jinnie because gold is purer than lead.

Septimus also orders Jim Knee to go and capture the Syren and force it into a small sealed bottle; hence Syrah is saved from her terrible enchantment.

However, learning that more than 500 years have been passed since she arrived there and that Julius Pike is long dead, Syrah enters a magical coma because of the combined effects of her recent dis-enchantment and the stress and sadness of this news.
