"All day, Will had felt as though something were watching him, something cold and implacable that loved him not. Gared had felt it too.Will wanted nothing so much as to ride hellbent for the safety of the Wall, but that was not a feeling to share with your commander." — The prologue to A Game of Thrones by George R.R. Martin.
I am not sure about the meaning of the bold sentence. Does Will want to ride for the safety of the Wall?
