The Nelumbu
This supplement introduces a playable aquatic plant species for the Cerulean Seas Campaign Setting and Pathfinder Roleplaying Game. The nelumbu are living water lotuses with bright blossoms, an industrious nature, and a coldly logical outlook. Neither inherently good nor evil, they pursue their own advancement and may ally with benevolent rulers or oppressive regimes. The book provides the rules and background needed to include this adaptable species in aquatic adventures.
