Ryūjin
The dragon god of the sea, ruling the tides with two jewels from his palace beneath the waves — ancestor of emperors.
In Ryūgū-jō, the coral palace beneath the sea, reigns Ryūjin, dragon god of the ocean, holding the kanju and manju — the tide-ebbing and tide-flowing jewels. Myth marries his daughter Toyotama-hime to the hunter Hoori; their grandchild is Jimmu, first emperor of Japan — the imperial line descending, by tradition, from the dragon of the sea. The palace features in the tale of Urashima Tarō, where three days below equal centuries above: the deep keeps its own time. Sovereignty over the tides, kinship with the throne, and a clock that humbles visitors — the sea-dragon's full portfolio.
The SGE Reading
Gift with its own clock: the deep grants jewels and lineage, but visitors must accept that its time is not surface time.
Canon Resonance
For the series' descents: whoever works in the deep must budget for the surface's calendar moving without them.
A Micro-Practice
Before any deep work (retreat, therapy, creation), tell someone on the surface how long you'll be gone — and accept the exchange rate.
