Lost Transcribing Crystal

Cog has informed Group Alpha that a Transcribing Crystal, ordered from Leomoth by its master never arrived.
Although Group Alpha initially believed the crystal to be something stolen by Sonas Fyrewood, and planned to investigate the Temple of the Emission once again, they soon discovered from Krolech Icebeard that several people had been heard discussing it near Westbrookes docks. Their names were Or Hammerdream, Elainis Hammerdream, and Vardon Bodz.
Deciding to investigate the island at the center of Lake Ioris, they questioned Mister Cornelius about any inhabitants living there. He informed them that a Tobias and Fon Cromwell used to live there, but did not know if they are still there. Upon discovering that there were criminals supposedly there, Mister Cornelius traveled to the docks alongside Group Alpha, and spoke to a friend of his, a woman named Kallen. Group Alpha agreed to pay ten dollars round trip for her to take them to the island, wait for them, then return to Westbrooke. They travelled over the course of 2 hours, finally arriving on the sandy beach of the island. There they discovered a cottage, and approached the front door.
Stepping inside, Group Alpha investigated and found a trap door beneath a bed. Venturing down, the encountered what appeared to be a smuggling den, filled with armed and hostile people. There was a battle, and Group Alpha emerged victorious. Locating the transcribing crystal, they returned it to Archmagi Kistarin Yvris, who thanked them and promised them that they would be first on the list for magic items.
