I have just played and prepped for this scenario so maybe it will play better than it did for me and will be a lot more fun, but this scenario was a bit of a disappointment for me.
I've been looking forward to this scenario for the longest time and it was the main reason I was pushing so hard to play through scenarios (unsanctioned or not) just to see how the adventure played out. Of all the locations that the series takes the party to, this was one that I absolutely was looking forward to.
In the end though, there was little interaction to be had from the scenario to make me feel like it was it was set on this location rather than any other. Maybe due to the restriction on length, but it didn't feel like there was really an opportunity to explore or play on this world, but that may be because I was hoping for a larger adventure here that the scenario couldn't support.
Barring that, the encounters came on pretty strongly, maybe I was unlucky to be hit with a crit but it killed my character right in the first encounter followed by another player's character. Since I was the only healer in the group and the scenario throws the party in such a place that they can't get any real options for raise dead, it would have been the end of the scenario if were playing this as a sanctioned scenario. The adventure just jumps to the next encounter and into the next. After losing two PCs in the first or second encounter, the game can't continue and the scenario doesn't give any way to recover from that aside from quitting.
Since we were not playing a sanctioned game, the dead character were brought back at a penalty and the game continued. The second encounter starts as soon as the first ends. If the party was having trouble with the first encounter, the second would finish them off given they have no time to heal between battles.
The adventure continues with a rush and gives high DCs to near impossible DCs to actually complete the adventure. While in our case this made it feel somewhat of a challenge that we had to do awesome to beat, if we replaced one character in the party it would have meant the end of the adventure.
It feels like there are too many abrupt ways this adventure can just end as well as there doesn't seem to be as much interaction with the world as I hoped.
