The three retreated rapidly while making sure the Moonlight Rabbit was lured toward the outside where the sun was already high in the air.
According to the Record of All Realms, Moonlight Rabbits will have their strength reduced by at least half under the daylight hence why the three decided to bring it outside the cave before attempting to kill it.
However, the creature was not completely a nincompoop either. After it noticed the sunlight at the end of the cave it realized what Khal and the two men planned to do, so it quickly stopped in its track but was quickly forced to continue its way forward because of the exploding wind blades.
Khal smiled. Upon seeing that the beast was incapable of escape he quickened his steps and approached the entrance of the cave faster than before while making sure to give no chance for the creature to escape.
