I’d love to see this expanded. The concept is cool, the setting is cool, the factions are cool, they just need some more space to grow in. The clock is interesting, but the lack of explanation (as others already noted) about what will actually happen once the Saurian King gets his ritual going strips it of its fangs. The clock itself would also highly benefit of some kind partial effects (like adding new types of monsters when it’s halfway or something like that). It also itches me a little bit that you mention “a safari spot for the wealthy and famous” and don’t use that at all, because it would have been a very cool addition to the general caos of your factions.
Plus, given how cool the factions and setting is, I’d love to see a bestiary for this adventure with appropriately jurassic monsters and researchers.
