As you venture through the world to discover the truth in this interactive fiction, you’ll gather equipment and forge your character. The lands of Tem Khiris are drenched in blood. You must figure out a way to survive in this world of warring states and rival tribes. Proceed with caution, for death lurks around every corner.

IN THE NEWS “A full-on RPG, complete with character progression, inventory management, and NPC interactions ... The character development and combat systems find that sweet spot between being too simplistic to matter and becoming a bloated distraction.” – Gamespace.com “Untold is a really solid and convenient package. It delivers feelings of grand adventure while allowing you to experiment and explore, and it does this pretty much all through text. It may not satisfy folks looking for a flashier, more action-packed experience, but Untold's restraint is exactly what makes it so impressive and refreshing.” – 148apps.com JOIN THE COMMUNITY https://discord.eldrum.com
