DM Level - You get all the current content (9 adventures and one encounter gallery): 5 adventures in the Dimgaard series (DG26 thru DG30) for 7th level PCs, the next 3 adventures in the Drow Conspiracy Saga (DC8 thru DC10), a new 1st level adventure (DGS14 Leather & Lace), and another Encounter Gallery (for 7th level PCs).
The whole nine yard - You get the current content plus all the previous adventures (25 Dimgaard adventures, 3 Dimgaard supplemental adventures, and 7 Drow Conspiracy adventures) - a total of 44 adventures.
Collaborator - I'm working through the 8th level Dimgaard adventures now. At this level, I'll provide you with the early draft of those adventures (before they are available in the next kickstarter) and we'll all collaborate on the direction of the campaign. These early drafts tend to be quite rough - basically my noted organized into something of a rough adventure. And you would need to get your thoughts, notes, and responses in to me rather quickly - a couple weeks at most - for me to incorporate them before the next KS finishes. I'll be adding a new section to the adventure format as part of concluding the adventure to list those who collaborated in developing the adventures.
Sponsor - Your generous support is greatly appreciated. At this level, I'll provide you with whatever I can within reason. I'm also adding a sponsor's section to the adventure format to single out those who have sponsored the adventures.
