The first savage tide has already touched the mortal world, yet none who live today recall this time of red ruin. Unleashed from the cruel heart of a fell seed, this savage tide swept over an ancient city atop the crown of a remote is island. The tide transformed beggar and noble, merchant and thief, resident and visitor into feral, ravenous fiends. The fruits of centuries of labor came crumbling down in a matter of days, and when the survivors tried to stem the tide, the resulting blast of power sunk their city into a boiling lake of death. Through it all, the Abyssal architects of the savage tide watched, taking pride in the ruin. Now, after a thousand years, those same masters look upon new targets, new cities beyond the horizon, compelled by the hatred will of their demonic lord to prepare for the coming glory. This time, the doom will not be limited to one hapless city. This time, all of civilization waits unknowing on the shore, blissfully ignorant of what the incoming tide brings.
