The Rainy City will be the setting for our "one of a kind" campaign framework. It's a place where each spell, magic item, and monster is (usually) unique, and where most of the real monsters are men. It's a little bit elemental, a little bit post-apocalyptic, and a little bit weird. It's meant to be a staging ground for an urban D&D campaign centered on robberies and intrigues.
It's the end of the world. It always rains. Rain beats against the walls. It seeps through the shutters. It pours off the mossy backs of the gargoyles. It turns streets into streams and rivers.
Teetering, damp towers lean against rotting townhouses. Servants dash through storms on petty errands. Fireplaces sputter weakly, and spellbooks filled with moldy spells rot in spite of the protections lavished on them for their precious contents.
The great school of magic used to be here. But that was before the world ended and the rains came. Now the old school is mostly under the bay, its secrets ruined and lore lost. Oh, a few of the highest towers peak out of the waters, testifying to its presence. Ferrymen use the towers as moorings and wayposts when the rain and fog make navigating the bay treacherous. But the school is from a past world.
But there is magic here. Wizards hide themselves away in their damp townhouses, each one jealously guarding the few secrets he still has, scrounging and scheming for more. The richest men live on the three peaks on the north bay, where the rains pour off the dark rocks in waterfalls. The poorest live in the sump, a low lying slum that is as much a swamp as it is a city. The desperate, striving tradesmen build their townhouses in rings that cling to the lower slopes of the peaks. Strange foreign merchants dock but rarely stay. The incessant gloom and rain drive all but the greediest or most hopeless men to move on as quickly as they come.
Rainwater pours off the backs and from the mouths of the gargoyles that decorate the stone towers and keeps. They plot too. Some say said they plot to destroy the city, but wizards sometimes hire them to keep watch over their petty secrets, anyway. Most find that rough men are security enough. Violence comes easily to them, and they care little for sorceries. But thieves can make a fortune here, if they are quick and clever. From the lowliest medium to the greatest wizard, the mages hire experts to steal spells and enchanted items from their enemies. And from their friends.
It's the end of the world. The rain never stops. And there's no one left to trust in but yourself.
