From publisher blurb:
UTHAE'OSH AT A GLANCE
At the beginning, there was the waterfall Vanth'a, and from her pool came forth the mists of creation, rolling out over the blank landscape. From the mist, trees and lakes and mountains grew, along with the Rhash'kyr, the great dinosaur gods. There was Mava'kan, the Furious Tooth; Ash'avae, the Deep Fin; Dabre'muunk, the Wide Wing; Xeke'nahm, the Gentle Mother; Gruurv'grankt, the Heavy Tail; Piraguun'zal, the Long Wisdom. From them came the first peoples: from Mava'kan came the elves; from Ash'avae came the dwarves; from Dabre'nuunk came the goblins, from Xeke'nahm came the ores; from Gruurv'granky came the humans; and from Piragun'zal came the giants. These peoples came to populate the world, which
They called Namu'tae, but great mists and mountains came to surround Vanth'a, and none could find it.
Play as one of the four new takes on traditional 5e lineages - Orc, Elf, Dwarf, and Goblin - or one of the two original ones - Protean or Phytoid! Uthae'osh is a city of wonder and excitement, with each of its six districts filled with enough adventure to keep any party active for a long time.
EXPLORE THE CITY OF THE GREAT WATERFALL AND EXPLORE THE SIX DISTRICTS!
For many centuries, trivial skirmishes and border wars were fought across Namuu'tae until a young member of the Dabrenajak named Teeko received a vision of a flowing waterfall and a woman's voice beckoning her to come and taste of the waters. Teeko struck out across the vast expanses of Namuu'tae, gathering followers as they came, until they finally found the great river Shash'va, and following it, she and her coterie came to find Vanth'a, the Waterfall of Life. Around Vanth'a, a glorious city was erected to protect her magicks and to show what the joining of all the factions could prove, and this city was named Uthae'osh. Today, the twelfth Tlantho - a drow named Stvolza kr Vorbyl - sits at the head of the Vanth'akuth, and the city of Uthae'osh has grown to become the center of activity in Namuu'tae. However, struggle is growing, as there are rumblings within the city about the Vanth'akuth and how tight their control over access to Vanth'a has become. And with new rumors of dangers in the northern mountains, the streets of the City of the Waterfall have become more and more challenging.
