For years, you have walked the path of the adventurer. You have explored every corner of Neir, venturing westward into Larass'hra... During all this time, the stars have continued to shine and the meteors to fall. And so, you have become convinced: it is time to step through a portal and embark on a long and perilous journey across the worlds of Nebvarasa. The Song of Nebvarasa is a supplement for La Notte Eterna 5e. This rulebook includes the mechanics of portals: where they are found, how to build them, and what happens when the ritual goes awry; descriptions of the worlds within the Dimension of Matter and the Dimension of Spirit; the detailed lore of Rengaria, the world of the gods, and their domains; six magic items; twelve new and powerful monsters; complete stat blocks of all deities to elevate your battles to truly epic levels; and the ultimate adventure, "Let There Be Light," complete with a dungeon where you can attempt the unthinkable: free Laon from his imprisonment and restore light to all of Nebvarasa.
