Task - House of the Autumn Rose [68+]

An ancient clan of goblin ninjas practices on the floating Thundercrest Isle. Known as the House of the Autumn Rose, these goblins are rarely seen and leave few witnesses of their bloody assassinations. The only warning they give of their attacks is to deliver a single rose to their chosen victim. Lieutenant Ekiltu found one such rose on his pillow when he awoke this morning. I need you to venture onto the isle and infiltrate the House of the Autumn Rose. Stop the assassins by any means necessary and, if possible, figure out who paid to have our Lieutenant killed.
