The Lich Queen's Beloved was a blast to play. Githyanki. What can I say...I like Githyanki. In the same issue is information for doing a 'Incursions' type of campaign in which the Githyanki invade the Prime.
The Razing of Redshore is hit or miss. First, a large portion of the adventure is underwater which may limit its appeal. Second, the adventure uses the premise that you need to undertake a ritual in some power node to advance above 20th level.....which may not be the case for your game if the transition from 20th to 21st is 'just another level'.
The Storm Lord's Keep. Our group found the adventure okay but not spectacular. A 'dungeon' in a unique location, the location (a sky castle that runs from 4000ft to 20,000 ft above the ground) which elevates the module from the mediocre.
