INTO LEGEND (TM) is a high fantasy tabletop role-playing game. It is purposely designed on the style of old world legends and fairy tales and classic fantasy fiction such as Lord of the Rings, The Shannarah Series, Earthsea, Narnia, and so on. It also retains much that originally made role-playing games so much fun, with magic-using trades distinct from other fantasy tropes such as the thief, the fighter, the ranger, the assassin, etc. It's a d100-based, modifier-centric system with a unique character-build path that calls for a minimum of randomization and maximum customization, allowing for the most control of the player in creating the avatar that best suits them. Each worldbook like this one is focused on a particular world, universe, or milieu into which the GM may transport his players for adventure, magic, drama, comedy, and immersive roleplay. Realms of Ia, Vol. I includes maps, deities, lore, creatures and monsters, additional player races, and other details of a fully-realized world full of danger, wonder, glory and legend for the players and their GM to explore, with plenty left for the GM to add to, enhance, and expand himself. This is the companion to the Into Legend (TM) Core Rulebook, the Into Legend(TM) Player's Reference, and the Into Legend(TM) Game Master's Reference.
