The Clan live in a strange undersea world, amid a cluster of nets and metal objects anchored to the root system of a giant plant. This is the Home and outside it lie the hazards of the deep - especially the voracious and many tentacled Horra. Their dead are cast out to sink slowly into the depths where the mysterious deity Ka is waiting.Now their environment is slowly changing. A new current is growing daily stronger and flowing downwards, drawing everything down towards the realm of Ka.
