From the RPG description here on RPGGeek:
Welcome to the world of Ehryn. After the fall of the second empire of mankind, the kingdoms of the eastern hemisphere have entered a renaissance. In a world of fantasy science, you can now play a collaborative story with your friends. The Legendary Realms Player's Handbook includes several customizable
modules to create a pen and paper RPG all your own.
Modifiers - A simple dice + statistics rolling system that also has great depth.
Expertises - Build a custom character with no classes or levels.
Aetherwarping - In a world of science, magic exists as a fearsome reality altering power.
Miracles - The Gods of Ehryn still make their resence known and answer the prayers of heir followers.
Technology - Many of the kingdoms have developed unique weapons that provide offensive ability to the weak.
Now is your chance to join the divided Elfs, quirky Dwarfs, or the myriad of Humans of Ehryn in new age of adventure!
(And an interesting note on the front cover: Trapped at a table.
Surrounded by nerds.
Low on dice.)
