The Letter

Today has been a tumultuous day, filled with both triumph and uncertainty. After settling some business in the city, I was approached by a new and unconfident lieutenant who shared troubling news about scouts not returning. I commended him for his diligence and assured him that I would report the matter to the proper authorities.
 
With a heavy heart, I made my way to the Temple of Waukeen, seeking solace and guidance from High Priestess Aria. Her words were a balm to my troubled soul, reminding me that darkness may dwell within, but there is goodness to be found and embraced.
 
My path then took me to Parvor who handed me a picture of Thalbin Mordell and Father Adrian Derosian, along with information about a ship named the Ice Breaker. I was tasked to take care of the individuals as well as the ship if possible.
 
My mission led me to the Ice Breaker, where I took on a disguise to infiltrate the ship and confront my targets. In a moment of swift action and determination, I eliminated the two individuals, but the chaos unleashed something unexpected. A mysterious cube fell out of a chest, releasing slaves held captive within. Amidst the confusion, I seized the opportunity to escape the lower decks with the cube, setting the ship ablaze. However, an enigmatic figure with horns and silver hair appeared, extinguishing the flames with a blast of cold magic. I managed to escape the ship, witnessing the city guards and cowled wizards giving chase after the ship, now identified by sails displaying broken chains and a silver dragon leading their retreat.
 
Back in the Goldspires, I reported the mission's success to Parvor and handed over the recovered item. He advised me to lay low for the time being, so I returned to my residence.
 
To my surprise, a black envelope awaited me, inviting my presence outside the grave district that evening. Intrigued and cautious, I decided to attend, seeking to unravel the mystery behind the unexpected summon.
 
As I reached the meeting place, I discovered others who seemed to share my predicament. Three mysterious figures introduced themselves as the Unbound, and the gravity of the situation deepened.
 
Additional notes:
Mezo, a trained soldier assisting his merchant boss, Thalbin Mordel, found himself involved in a clandestine delivery to a drow merchant ship. Intrigued by an old book at the Lazarus Library about Refrin and lycanthropic dealings, he delves into its secrets. Soon, he too receives a letter summoning him to a meeting outside the grave district at nightfall.
 
Ellis, returning home with his friend aboard the Ice Breaker, sought to surprise his parents with their unexpected arrival. A delightful meal was shared, but as the evening progressed, Ellis followed his friend to a meeting with a person of gold rank, heading towards the slave district. He too received a letter, shrouding his day with further enigmatic intrigue.
 
Haldir's musical prowess amazed the audience during his performance, attracting the attention of a Lord who spoke of mysterious mines in the East. Later, the Dannihyr family summoned him to interrogate an individual with knowledge of a ship carrying peculiar elves and a shrinking device. The task was swiftly dealt with, and like the others, Haldir received a similar letter.
 
Mavros, meanwhile, found himself at the Church of Lathander, engaging in a brief conversation with Father Derosian discussing morality in the name of good. A blonde boy arrived to retrieve a letter from Father Derosian, leading Mavros to follow until the boy arrived at the drow ship, identified as the Ice Breaker. After sharing the information with a handler, he too received a letter.
