Fontaine opened the book.
'Hello Welcome to Your Guide through the deep.
I will be your personal helper with all that you need. Be warned only the Nekton Who is reading right now will be able to harness the true powers of the ephemycron. Take the magic quill.'

A quill popped out of the book.
'Write your name. Ah Fontaine Nekton. Welcome. Now would you like to learn about the powers you hold with the ephemycron.'
Not right now. She wrote. Right now she didn't have time to think about any powers she could possibly hold. Right now she only cared about finding her family.
'What do you require help with. I am here to serve you. Ah finding your family enter the riddle my dear.
Find me low in the deep below
Find me high in the sky
Sail through the hail
To the heart of the grove

Tranaslating

Find them underwater or above
Sail though a storm
Find them in the centre of something

She stared at it gobsmacked.
"Ok" she showed Finn. He read it and nodded.
"Ok so what do we do now?"
"Let me try something?"
'Fontaine there is no exact location for this riddle. It is not specific enough. Would you like to learn about the Ephemycron Magic??'
'Fine'
'As the elder sibling you have the power to summon the ephemycron. You also have the power to use the ephemycron for things you need or want. But if you use these powers for selfish gain you will end up slowly but surely turning evil' she stared at the page in utter shock.
'How do I summon the ephemycron?'
'You simply say 
With the power of the seven seas I call you to me
Ephemycron here!

Oh and have your hands ready to catch it'

"Ok let's try this. 'With the power of the seven seas I call you to me. Ephemycron here!" Suddenly the ephemycron appeared in her hands. She smiled and Finn stared at the object now in her hands. His jaw on the ground.
"H-H-Ho-www you do that??" He stuttered. Fontaine was staring at the ephemycron shocked too.
"I-I don't know"

Alpheus

Alpheus smirked at Ant.
"We could of been partners you know"
"Like I'd ever want to work with you!!!"
Alpheus still smirked. He looked over to ephemycron sitting happily on the table. "Wherever you take us Fontaine will find us"
"Doubt it. You see I know exactly what she's doing. She'll be to scared to do the thing she has to and thereforth will never find you" Suddenly Ants smile grew. "What!!" Alpheus demanded. He turned to where at was looking. The ephemycron was gone.
    "WHAT NO!! SHE DIDNT!!"
"She didn't what?"
"None of your damn business"

Fontaine

"I think we can use this to find my family"
"What is it?"
"The ephemycron. An ancient Lemurian Navigational device"
"Your family and Lemuria"
"Oh shut up"
"Nope"
"Your family and treasure"
"Shut up" Finn grumbled.
"Oh cheer up. I don't want to deal with a grumpy baby"
"BABY!! Fine I'll stop. If you give me a kiss" he smirked. Fontaine gagged.
"Do you want me to punch you?"
"You wouldn't"
"Try me" She readied her fist and Finn ran away screaming like a baby. Fontaine chased him.
"Get away from me crazy lady!!"
"Not until I've punched you!!"
