Rather than a string of encounters, one per week, that form a linear adventure, this booklet presents a series of short adventures incorporating elements of exploration, interaction, and combat in roughly equal measure.
All the adventures offer much more flexibility than the linear adventures of the past, and each is designed to be played in a single session. Taken together, the adventures tell the story of the War of Everlasting Darkness—the conclusion to the Rise of the Underdark story that has played out throughout the year.
One of my concerns is leveling after every session. I can see it causing confusion when someone stops by for the first time with their level 1 character only to find out everyone is level 6. Also, how will pregenerated characters work? Before you could give someone a lvl 1 pregen even at the end of a season and they would do all right. I hope a leveling guide is provided for pregens.
