If you don't mind a lot of converting there are some old modules designed for high level as well.
The only module I've seen that goes to 100 is back in 1e; good old H4 Throne of Bloodstone.
Gokijin said:I hope this is the right thread to ask, but isn't there a module that takes characters from level 1 to 100 for 3.5? I understand the difficulty it takes to create high level campaigns and we have done a few, but the amount of preparations needed take up all the free time for whoever is DMing. But at the same time, we play a character from first level to near epic or epic and then have to start over because we run out of material and after months of playing the same character, its hard to set them aside sometimes.
