This is a version of Ythrek formatted specifically for the iPad, and optimized for use with the GoodReader app, available on iTunes. It has full hyperlinks and bookmarking, and an added navigation bar for quickly moving between chapters. If you already have Ythrek, you can get this version for $1. If you have not seen Ythrek or EABA, read on:
Ythrek is a resource-poor Renaissance world with magic, honor and a very harsh climate based on several overlapping cycles that go from searing to freezing as the decades pass. It has been eight hundred years since the Cataclysm that nearly tore the world asunder. So few survived that even the nature of the disaster is unknown. But, from the accounts of the Spirits and the survivors, and tales brought by traders, things thought dead but only sleeping have begun to awaken. The spring decade is upon the people of Novomad, center of Ythrek's civilization (at least they think so). The weather once again permits travel to lands out of touch since the start of the long winter years, and the squabbling scions of the Six Families once again seek fame, fortune and Ancient knowledge in the wastes outside Novomad's fertile valleys.
Ythrek is a supplement for EABA, not a standalone rpg product. Although you can use the setting with other game systems, it is meant for use with the EABA rpg (also available in iPad-specific form).
