History
"Goodness. I ... I dropped the cookies. How silly of me."

-To Percy and Nico in The Last Olympian

May Castellan was a clear-sighted mortal who also possessed the gift of prophecy. Hestia stated she had many talents and Percy said she carried a kind aura. She attracted the attention of Hermes and they began a relationship. They had an adorable baby boy that she named Luke, and for a year or so they were happy.

However, May had the ability to see through the Mist like Sally Jackson, Maria di Angelo, and Rachel Elizabeth Dare. Hermes told her how the Oracle of Delphi couldn't take another host and May believed she could take the spirit. Hermes also didn't support May's decision because it meant that the two would be parted forever, as per the laws of the Oracle of Delphi. However, Hades cursed the Oracle decades ago and the spirit of Delphi was trapped within its current body.

May tried to take the spirit into her body but as a result of Hades' curse, she went insane and went into constant episodes about Luke's fate. She saw that he would hold Kronos inside himself and all the atrocities he would commit.

She would make peanut butter sandwiches, cookies, and Kool-aid for him, constantly thinking any boy to come by would be Luke. She also had many wind chimes and beanbags of monsters. He came to her and asked her blessing so that he may be treated in the River Styx and Percy and Nico arrive to discover just how he had done that.

She remained in her crazed state at the end of series. It can be inferred that her insanity can be cured by Dionysus, but this is doubtful as he had many years to do so. It is possibly that her crazed state is beyond Dionysus' power as her insanity was caused by a curse placed on the Oracle by Hades.
