Velociraptor's Grave

From the introduction:

Velociraptor's Grave is a freeform LARP about a long-dead dinosaur. Most ghosts last only a few centuries at most before they are willing to move on, but this particular saurian has hung around for over 70 million years. It’s time for this ghost to release the energy that binds its spirit to our world and allow its very essence to spread out into the universe like so much stardust.

It’s just going to take one last opportunity to say good-bye to earthly things. That’s where you come in. Whether you like it or not.
