Toltep walked slowly along the avenue, it would have been easier to swim along in the viaduct, but he had made it a point to not do the easy thing. All to often the easy path lead to ruin, and he had not survived so long by taking shortcuts, or the easy road. The market, what was above water, was abuzz with conversation. A large school of blood-crazed lurdi had been diverted into an ambush where the brave people had slaughtered the monsters. There was some worry, Toltep gathered, as a few had escaped.
A rumour of the knights of some powerful king that sleep until danger threatens the kingdom.
The truth is that they were rebels, trying to split the kingdom. Once captured they were put into an enchanted sleep, protected from age and harm, until their aims have been carried out by others in which case they will awaken.
There is a loophole in the spell in that trying to take one of their weapons will also awaken them.
