Peter noticed that the commotion at the pond had stopped and left back to the crystals. When he left he had heard the goblins talking about how he didnt put up a fight. Since they have no expectations now he  comes behind them and shoots em with some mana orbs. Since two mana orbs would probably run him out of mp he quickly grabs a piece of the mana crystals and uses em to regenerate his mp. If the goblins still can harm him he launches more orbs at them.
