The tokens are part of the module, you don't get the art assets by themselves with a module. From the module store page: Included in the Roll20 Module edition of Storm King’s Thunder: Over 250 hours of campaign preparation completed for Roll20 users Over 200 statted Tokens featuring original artwork from Dungeons & Dragons. Over 40 battle-ready Maps. The module is advanced feature-enabled, with Dynamic Lighting on 22 Maps. Cross-linked handouts throughout the adventure. A grand story full of replayable adventures, including the largest Dungeons & Dragons 5th Edition battles ever. Over 160 locations in the Forgotten Realms! You get it all prepped and ready to go, but the assets (short of using the character vault or transmogrifier) are not transferable from game to game. As far as I know this is the way it works for all modules. I am of course, not connected to Roll20 and have no official standing for giving their answer to this question.
