I noticed 2 huge black ravens in the lower branches of a weeping willow, perched perfectly, motionless, like creatures in a tapestry. Their very stillness gripped me with a strange fascination. I could not shift my eyes from them. gradually the forest sounds receded into the distance as if I were slipping into a dream........
The ravens flapped enormous wings, lifted into the air and flew downriver straight towards me, but they continued to speed low over the water and, at the very last moment, I had to duck my head beneath the surface. The Ravens passed inches above me, their wings beating like the great, groaning oars of raiding ships. Gasping and spitting river water I turned to watch them fly away. I stared in bewilderment at the spot where they had vanished.
"Death bonds will stalk someone tonight"
I started at the sound of Wulf's voice. Then my ears popped and the sounds of the forest clapped back into my head like the chapel bell.
"The Ravens have spoken to us, Wulf said severely. When birds fly like that it is a powerful omen. A warrior will die tonight"
