The lake had turned out to be utterly deadly. Even after preparing thoroughly for the battle against the terrifying creatures that dwelled in it, the Sleepers led by the young knight still ended up losing one of the rafts — they managed to pull a couple of people out of the water, but the rest were pulled into the depths, never to be seen again.
The clear water was painted red with blood.
The rest of the rafts only survived because they were crafted from the unnaturally sturdy wood of the cursed forest with the help of their leader's Aspect. Otherwise, there would have been only drifting splinters left on the surface, with all traces of the Sleepers washed away by the clear water.
Even then, the journey had not been easy for those who survived. By the time they reached the walls of the castle, each and every one of the Sleepers was bloodied, barely conscious because of exhaustion, and numb from terror.
