They held a staf meeting , to discuss plans , so one orc, named grub, decided that it was the signs that the time of the prophecy had come but the others didnt think so. So Grub struck out on his own but captured some other orcs and ex-sanguinated them,and sacrificed them to the corrupted nature spirits giving him powers of haemomancery, but the orcs caught on to him. and in a fierce confrontation between Pakuna and Grub, Grub got beaten and exiled
Later Grub stumbled upon one of the portals in his time in exile and entered, seeking more power! he joined Ursoth's Army and when he heard of Korgar's death , he thought it was the perfect time to strike again ,so he riled the corrupted armies and corrupted more elondrian wilds, making more arcane beast (the squirrels and Unicorns) flee and join our side.
