"And how are we meant to have contact with your sister?" asked Regina.
"Iris messages." replied Jason. "A communication spell in which we can have contact to anyone in the world."
"How far can it stretch?" asked Emma. "Can it cross realms?"
"We've never tried." said Leo.
"Well how do we enact the spell?" asked David.
"Well we have to make a rainbow and give an offering towards the Goddess of the rainbow - Iris. Once we have the rainbow, we throw a golden drachma and we make contact after the offering." said Percy.
"But all magic comes with a price in our world and the magic in Storybrooke certainly comes with a price." said Dr Facilier.
"Well we're just going to have to pay it." said Annabeth.
They headed towards the park and they created a rainbow by shining light from a glass tube filled with water and Percy threw a golden drachma and muttered the incantation but nothing happened.
"Thought it may happen, lad." said Killian.
"When did you get here?" gasped Piper.
"Pirates need to be stealthy ya know." replied Killian.
"But why isn't it working?" asked Hazel.
"Because Iris is dead." said Dr Facilier. "The God Killer got to her."
"Who?" asked Mary Margaret.
"A true legend about the God Killer. A mystical hooded figure who has the power to kill Gods. No one knows who or what is under the mask but is truly powerful."
"I've never heard of this before, tell us more." said Regina.
"It started aeons ago when the wife of Zeus - Hera - went missing. The couple loved each other until she went missing. The Gods searched for years but there was no luck. One day, another Goddess was gone but she was found only not alive. Athena died that day and that's when everyone knew of the God Killer. Mostly it is the one doing the killing but sometimes it whispers into peoples ears and give them the power to kill a God."
"It's an old wives tale." said David. "It can't be true."
"But it is." said Zelena. "The day I killed Hades; it was as if I was guided by a being. I haven't thought much of it until now but it makes sense."
"Look we can't go around for assumptions." said Rachel. "It might be fake."
"But many Gods and Goddesses died. The God Killer's goal is to end the Olympians but it will kill any God that stands in their way. Athena, Hecate, Iris, Hades, Aphrodite, Ares, Hephaestus, Hebe, Persephone, Amphitrite, Dionysus and Eris have died due to it. Eight Olympians remain." said Dr Facilier.
"But there are only twelve Olympians." said Nico.
"No, here there are fourteen. Hades and Hestia still have their thrones." replied Regina.
"But what does this have to do with the Iris message?" asked Percy.
"Isn't it obvious? You're giving sacrifices to a dead Goddess." said Dr Facilier. "I'm afraid they just won't work."
"Then how are we going to communicate with the Huntresses of Artemis?" asked Piper.
"Perhaps we just need a different method." started Regina.
"What do you have in mind?" asked Emma.
"Mirror magic."
"I thought in order for it to work you need to have a mirror to whom you want to communicate with." said Leo.
"And I thought you gave that mirror to Belle when she left for Wonderland." said Jason.
"Then we are going to have to meet someone who knows about mirror magic the most." said Regina.
"Gold's not on our side." said Annabeth.
"No, not Gold." said David. "We need to find Sydney Glass."
