Abdul Alhazred came to the Land of the Green Isles when he learned about the place from a copy of The Guidebook to the Land of the Green Isles. King Caliphim and Queen Allaria were impressed with his knowledge and made him Vizier. While being Vizier of the kingdom, he ordered his genie, Shamir Shamazel, to steal each of the islands' sacred treasures and spread rumors that each island was involved in the other island's item being stolen.
Alhazred was regarded as suspicious by the people of the Land of the Green Isles. It was through his trust with King Caliphim that he retained his position as Vizier. When Cassima was born and grew to a young age, Alhazred saw this as an opportunity to his plans and immediately took a liking to her.
At some point, his friend and master, the wizard Mordack, came to the Land of the Green Isles and was introduced to Princess Cassima. Mordack wished to marry her, but when she refused, he kidnapped her, with help from Alhazred, and took her to his island castle. This devastated the king and queen, and according to Alhazred, they became ill and died (though he actually murdered them), before Cassima was sent home after being rescued by King Graham of Daventry.
Alhazred made plans to marry Cassima (and then murder her like he did with her parents), but Prince Alexander managed to stop the wedding. Alexander discovered that the wedding was a fake, since the bride was actually Shamir transformed into Cassima. Alexander took Shamir under his control and followed Alhazred at the peak of the castle tower. He then engaged Alhazred into a sword fight. When all seemed lost, Cassima stabbed Alhazred on the shoulder when he was not looking. Alexander knocked him out with the ceremonial sword by smashing it over his head. When he Alhazred recovered, he was escorted by two guards to the dungeons and would stay there for a very long time.
