BGSJ is a setting about exploring an ancient crocodile's memory palace. From that humble beginning, it has sprawled. There is a game setting under there somewhere. But presenting it has proved difficult.
The potted history of the setting is that said crocodile has been alive since the Triassic period. During its life it has roamed far and wide across oceans, seas, and freshwater systems, and created a memory palace to store its knowledge of all the things that it has seen. But it has recently gone into a period of quiescence - a long slumber in its old age. During its sleep it slowly sifts through its memories, and dreams about its life, as it slides inexorably but glacially towards death.
Approximately 50,000 years ago the Naacals, the inhabitants of the lost continent of Mu, discovered the sleeping crocodile in a small freshwater lake (in what we now know of as New Guinea). A group of their philosopher-mages discovered a mechanism for entering its memory palace. They used this as a means of escaping an apocalypse which they were predicting, and they moved into the memory palace wholesale. There they constructed a city ("The Unremembered City", because it was the only thing in the memory palace which the crocodile did not actually remember) and used it as a base to explore. They discovered that the crocodile's "palace" is really a world: a huge ocean full of strange lands, beasts and places which the crocodile remembers - and which have slowly become warped and strange over the many millions of years which separate the actual events from the memories themselves.
The apocalypse came and caused the continent of Mu to sink beneath the sea, leaving only remnants of the original Naacal civilization behind (who went on to find civilizations in India, Egypt and Mesoamerica). But the Naacals in the crocodile's memory palace continued their exploration and colonisation of the lands they found there, and created a new civilization of their own within it.
However, since time stands still in the world of memory, these Naacals effectively became trapped in a static environment. As much as they enjoyed exploring the memory world, and constructing things within it, they eventually became bored, listless and decadent, and finally their civilization too collapsed. A few remained sleeping in The Unremembered City; others scattered across the memory world to pursue esoteric goals and lost contact with one another.
Fast forward 40,000 years in the outside world and newcomers came upon the crocodile and entered its memories. In order, they are:
- Xu Fu - an ancient Chinese magician/courtier/sage who went in search of the Elixir of Life at Mount Penglai
- Pape Jan - an Ethiopian king who went to spread the word of God among the heathens of Asia
- Abu Yaqub al-Sijistani - a Persian Neo-Platonist who went abroad to spread Truth
- Anak Wungsu - a Balinese merchant who went searching for new luxuries to trade
- Jorge de Menezez - A Portuguese conquistador who was wrecked in New Guinea after a life of rapine and slaughter in the Spice Islands
- Ebu Gogo - a diminutive hominid from one of the Spice Islands whose people were all massacred by conquistadors, who fled and began looking for a new home
- Sese-Mahuru-Bau - a New Guinean hunter who went into the jungle to search for a dowry to give to the father of his beloved
Each of these people came to a different region of the memory world and began to transform it inadvertently in their own images, implanting their own needs, desires, hopes and fears within it - so that their individual goals began to transform they stuff of the world itself and warp it into something else entirely. So:
- Xu Fu came to an area of placid sea dotted by tropical islands and discovered within it Mount Penglai - an impossibly tall mountain inhabited by dragons, a phoenix, and other creatures from Chinese folklore, as well as things and peoples that he saw on his journeys around the Pacific Rim
- Pape Jan came to an area of bushland featuring the crocodile's memories of early humans, and discovered within it tribes of pagans, each with their own devout belief systems, and each in need of conversion; he also found there Solomonic or Goetic demons
- Abu Yaqub al-Sijistani came to the crocodile's memories of the aftermath of the meteor strike which killed the dinosaurs, now inhabited by the surviving avian dinosaurs and the ghost and wraiths of those that died, and discovered in the midst of the chaos all of the Neo-Platonic philosophers pursuing theurgy
- Anak Wungsu came to a shallow sea where in the distant past the crocodile witnessed ziggurats constructed on the seabed, made by aliens, and introduced the notion of commerce to the remembered alien civilizations there
- Jorge de Menezez came to the crocodile's memory of an ancient Atlantean city which the crocodile mistakenly believed to have been inhabited by birds, and found it to be a new place to raise an army with which to carry out further conquests and set himself up as ruler of the world
- Ebu Gogo came to the crocodile's memory of the carboniferous swamps of distant eons, and there began to breed with the amphibian inhabitants to create species of hybrid spawn to be her new people
- Sese-Mahuru-Bau came to the crocodile's memory of an ice age, and transformed it into a hunting ground dotted with patches of mountainous jungle amidst the glacial ice
And also, inadvertently, these intruders also awakened the Naacals sleeping in The Unremembered City - who have now woken to discover a world very different to the one which they had originally discovered. The PCs are from the younger generations of these Naacals, who have now once again begun to reproduce and spread across the crocodile's much transformed memory palace.
The presentation has changed quite a bit but I now think I have a fairly good structure with which to proceed. The key is avoiding too much infodump; so much so that I am now strongly leaning towards not actually having any of the above background fluff in the book itself. I instead intend to present the world "as is" and let individual DMs and players figure things out for themselves. They can of course stumble across my blog entries on it, but there is a lot more depth to the background than what I have presented here.
In other words, basically it is 7 different "planes" of weird stuff to explore, that is inspired purely by real world history and folklore and my own corruption of those things, and not by any existing fantasy setting of any kind. At the centre is a city with a pseudo-Egyptian/Mayan flavour, from where the PCs derive.
