You turn in the Miniature Sword to Sirran The Lunatic and get the following:
Sirran the Lunatic says 'These are the keys! Use them well! Hold them in your hand and touch them to the runed platforms! Guide you they will! Hah! The last to go, must tell me so, or be in for a [hassle]. If there is a hassle, I will go.'
The Key of Swords https://everquest.allakhazam.com/db/item.html?item=21651 appears in your inventory and is the key to the Dojorn Isle.
I tried several variations for the trigger [hassle] and got no response whatsoever.
