RPG Vault have been lucky enough to bag a series of diary entries from the folks at Ossian Studios, leading up to the release of MoW. Take a look at the first entry:
Westgate Location and Lore
Having set our previous Neverwinter Nights game, Darkness over Daggerford, in the small and sleepy town of Daggerford along the Sword Coast, we scanned through many places in the Forgotten Realms in search of a location that had a well-developed background and intriguing lore. We also made notes on the places that fans had been requesting in the community for an official Neverwinter game.
We were looking for something that was at the other end of the spectrum from sleepy Daggerford, something that bustled with danger, and that would fire up a lot of excitement at the mere mention of its name. The city of Westgate along the Dragon Coast fit the bill very well. I'll let Luke talk more about some of the sights of this locale that convinced us it would be an excellent place to set an adventure.
Mysteries of Westgate is a single-player game that starts the player off at level 8. It is very much an urban-based adventure, with a number of different districts that the player can explore within this city of corruption. Players can look forward to 15 hours of gameplay with a branching core story and, just like Darkness over Daggerford, plenty of side quests.
