While lightning may strike anywhere, there is but a single Temple of Pure Lightning. This temple could be located just about anywhere – out in the middle of an expansive dungeon or even hidden beneath the streets of a bustling city. Regardless, this temple is not for the faint of heart. Within these walls are floors charged with lightning, ancient powerful weaponry, a vast series of winding powered minecarts, and rooms that are filled with eternal storm clouds. Just as dangerous are the aetherspawn that have been drawn to this place of great power and now see it as a home that will not be taken from them by the likes of a few mere adventurers.

The Riverlands Kingdom is a peaceful place. Generations ago it was a thriving and rich trading empire. Now it is a sleepy region of farms and a few craftsmen. Dotted with villages and a few towns along the numerous rivers, protected by a wall of rugged mountains, a wild forest and a vast steppe, little of note occurs here from generation to generation. All that is about to be shattered, an ancient evil has arisen and undertakes to bring wrath and destruction to the Riverlands in a pledge to conquer the rivers and kill those who reside between them. The peace is about to be shattered, the harmony destroyed, the balance disturbed.

The Therayle farm, which has been in the family for generations, was the best producing in the region. It now faces ruin. Hugh Therayle, the current owner, is at wit's end trying to reestablish even a modicum of control over the disrupted land. But, when Hugh saw the ancient doorway jutting up from the middle of the field where his corn used to be, he knew that this wasn't the type of problem a plow could solve.

The weave, which governs all magic on Toril, reacts strangely to the fragments. More information existed before Houn destroyed his research and fled Thay. His current whereabouts are unknown but many of his peers have attempted to track him down and steal his research for themselves.

Sometimes it is the simplest of tasks which end up taking much more of time and energy than they should. When the party is asked by the local sage to collect some rare flora, it feels like relatively easy money; a journey into the woods they’ve traveled before, a conversation with someone they’ve met before and then on to gather the crop. The characters can hear the Thirsty Serpent tavern calling them after a brisk afternoon’s work. But the PCs’ plans go awry when it turns out nothing is quite that straightforward. Deals have to be struck, foes defeated, anger and scorn dealt with and then the whole process gone through again. When there is duplicity at every turn and double-crossing is done with relish, the PCs have to keep their wits and weapons equally sharp. Dealing with someone who is prepared to cross the line between humiliation and harm at a moment’s notice is a tough challenge; this quickly becomes about much more than mere mushrooms!
