Soar above a planet of adventure! The trail of a long-vanished ally leads to the other side of a magical portal called the Doorway to the Red Star. The heroes must earn the trust of the portal's guardians then travel through it--to another planet of red sands and high adventure! Working to gain allies among scholarly brain-people and shifty ratfolk, the heroes must infiltrate a massive airship and fight to free their ally from an insidious trap on an alien world! "Doorway to the Red Star" is a Pathfinder adventure for four 15th-level characters. This adventure continues the Strength of Thousands Adventure Path, a six-part, monthly campaign in which the heroes rise from humble magic academy students to become influential teachers, and ultimately decide the fate of the Magaambya. This adventure also details people, places, and monsters of Akiton, the Red Planet, a fabulous setting for sword-and-sorcery escapades! Each monthly full-color softcover Pathfinder Adventure Path volume contains an in-depth adventure scenario, stats for several new monsters, and support articles meant to give Game Masters additional material to expand their campaign. Pathfinder Adventure Path volumes use the Open Game License and work with both the Pathfinder RPG and the world's oldest fantasy RPG.
