Time Scrying

"There's an old story of an arrogant young mage who learned the ability to see the future. He tried to use this knowledge to build a fortune.  He would learn the outcome of arena matches and then place his bets on the winner.  However, each time his combatant lost.  He tried and tried, testing all the variables he could, until he found himself penniless and destitute.  He had learned the hard way the truth about the future: it was uncertain, and just knowing the future course of events was enough to change them." -Paris

The ability to predict the future is the only knowledge that is expressly forbidden from study by Solon becuase it is impossible to truely know the future, just trying is enough to change the future course of events. During his training to become Dragon Speaker, Paris became curious about this type of "forbidden" magic and took it upon himself to study it. What he learned shocked him.

He predicted a future ruled by Demon Lords, where the last bastions of good fight a losing battle against the Demon's total dominion. It would seem that the War of the Martrys distracted the dragons completely from the rising threat in the east, past the Dead Marshes, where the demons where building thier power base. When the demons finally did launch thier assualt, the dragons refused to give up thier own war in order to counter them. The actively fought and even sabatoged one another's efforts to fight the demons, making the demon's conquest almost without challenge. The last city of mortal control was burned to the ground by the dragon's fighting, leaving the Demon Lords nothing to do but march across it and declare total victory.

Paris wanted to prevent this from coming to be and approached Li'liok with this information. He said the war needed to be stopped so that the people could prepare for the impending invasion by the Demon Lords. Li'liok was furious. He declared Paris a traitor and Paris barely escaped with his life. Since then, Paris had worked to prevent this future from taking place.

Over the course of the adventures of the Party he sent them to this future so they could see for themselves what would happen if they failed.
