When the twins informed Eon of their plan, they thought for sure that he would say that it was a dumb plan or something. Much to their surprise, he actually agreed to instruct them on how to get to the dream realms physically.
"First you must go through the city of Darkness. Skylanders of the dark element are strongest in this zone." Harmony and Kaos frowned. They didn't need to be geniuses to know that one. "There you must collect sleep shards from the city's inner sanctum; the Crypts of the Banned. You must use extreme caution as there is said to be some strange sort of creature guarding it, or at least there was. About two hundred years ago, something happened to the creature guarding the crypt, so I am unsure of where it is or what it looks like. No one ever ventures there."
"Shall I say the thing on my mind that's most obvious but might not be?" Harmony asked as she looked at her twin.
"If it's that Glumshanks might have been the guardian than you and I are on the same page. Let's go." He then called back to the older light portal master. "We'll get the stupid sleep shards, don't worry, Eon." Harmony was right behind him talking about the possible ways to get there and asking about the possibility of summoning without a portal like what she had at home.
The two had decided to have Spyro and Cinder fly them there that way the two could get flying practice, and Flynn didn't need to take them everywhere. Besides, riding dragons was something any kid from Earth would be jealous of!
