Grimm kept on flying for seven days.
On the eighth day as he was flying away from Bramble Forest, ten crows besieged him, attacking him with wind blades and petrifying lights (lights that could peg down the ones attacked.)
The crows had three eyes and the third one was worth studying for their ability to petrify living things. If it was not for the fact that Grimm was on a mission, he would engage and capture some for their eyes.
Instead, he dodged, steered away from them and headed towards the destination. Temporary interests must be sacrificed for the greater purpose.
The crows stopped their hunt after having lost their target.
