Banestorm (4e)
A realm of magic and faith¸ on the cusp of the 21st century. An aged¸ stagnant Anglican empire¸ diminished in stature¸ rife with internal unrest¸ vulnerable to neighbors it threatened to swallow whole three centuries before. An extremist elven faction¸ routed but still lurking in secrecy¸ bent on magically purifying the land despite the previous attempt having nearly torn the world asunder.
And an ancient cross-dimensional riptide ‐ the twisted result of this small¸ genocidal fellowship's massive spell gone wrong ‐ that erratically swells and recedes¸ swells and recedes... snatching hapless seafarers and even entire villages from our world and other¸ stranger places¸ depositing them into the conflicted land of Yrth.
In your hands rests Ytarria revisited and revised. Bigger. Better. And updated to work with GURPS Fourth Edition. All you need to not-so-safely wander the urban and rural wilds of Yrth is this book¸ the GURPS Basic Set¸ and a yen for adventure. Discover the details of Ytarria's history. Meet the new immigrants from the watery world of Olokun. Peruse the newly described underwater realms and the southwestern wilderness. Caithness is mired in civil war; new secret societies abound. There's lots more on magic¸ mysticism¸ and alchemy¸ all of which conforms to the just-released GURPS Fantasy and GURPS Magic.
