Probably an inside joke by the developer turned retail product, this little missionpack brings the less than epic conclusion to the cliffhanger of the original ArcaniA. It is like somebody scraped together a bunch of unfinished questlines and maps from the maingame, mashed them together and called it a day. It took me about 2 hours finishing this using the endgame save from the maingame and it is pretty much more of the same, but somehow worse - because the writing feels like they just did not care anymore, with many misguided attempts at comic-relief killing all sense of atmosphere.
Considering it is stand-alone, it might work as a sort of quick fix if you crave some mindless hacking and slaying but want to be done with it all before dinner. It carries all the issues of the maingame (boring dungeons, crappy combat-system, lots of crappy loot) and doesn't bring the closure to the ArcaniA-chapter of the Gothic-Saga that I had hoped for. Pretty much a waste of time and money unless you played all the better alternatives.
