from the introduction:
Long Night at the Black Swan is a Dragon Warriors scenario for a party of 4-6 1st Rank characters. It has been designed as an introductory underworld adventure for a group of beginners, and can be run as is. However, experienced gamers will find that there is plenty of scope for additional non-linear strategy and complexity as well. It is recommended that at least one (and preferably more) of the characters is a member of one of the arcane professions (a Sorcerer would be ideal).
designer's forum comments:
Was browsing through my old files and discovered this Dragon Warriors adventure. James Wallis originally commissioned it for publication in Mongoose Games' Signs & Portents magazine but chose Betrayal at Desolate Mountain instead (probably because I missed my deadline!).
It's a short beginner adventure set in an underworld beneath the Cornumbrian city of Criggen Varras, with possibly too much scope for initial expansion (you've really got to come up with a second level to it straight off the bat).
Still, if anyone uses it, let me know how you go because I never managed to run it myself! :-)
