Centuries ago, a wave of fast-growing plant life toppled civilization. Now the descendents of the survivors live on high mountaintops, excessively tall trees, and spits of land pushed up to the top of a mile-high forest that now covers the world.
You and your companions are Wildsailors, a motley crew of humans, walking cacti, shipwrecks given form, spider hive-minds, mobile fungi, and flightless moths. You travel from port to port on chainsaw-driven ships, trading goods and seeking adventure. Whatever your motiviations, your travels tie together this new civilization.
The Atheneum began some ten thousand years ago as an enterprising and particularly meticulous nano brought together a small collection of artifacts and books, building a small datasphere interface to link them together. Since then, the collection has grown and taken on a life of its own.
The Librarians work constantly to keep the Atheneum safe and useful.
