Mollie's Arrival
A Junior Trader with the Grand Maritime Union, Mollie climbs the ranks and earns herself enough reputation within the company to be tasked with bringing a fleet of ships to the Sea of Thieves in order to establish dominance.
The fleet is unsuccessful in passing through the Shroud, with Mollie's ship barely making it through. As they arrive they are attacked by pirates and Mollie, along with a few other high ranking members of the GMU, are left to fend for themselves with only a rowboat and meagre supplies. They manage to row to a nearby island where, after spending a night there, Mollie finds herself abandoned as her fellow GMU superiors absconded with everything of value. She does manage to convince a group of passing pirates to let her come aboard in exchange for her doing her bit on the ship.
