IOI had created a new department within the company that they called their "Oology Division." ("Oology" was originally defined as "the science of studying birds’ eggs," but in recent years it had taken on a second meaning: the "science" of searching for Halliday’s Easter egg.) IOI’s Oology Division had but one purpose: to win Halliday’s contest and seize control of his fortune, his company, and the OASIS itself.
