Birth by Sleep Master Xehanort's seeds...

Hi all,
In the secret ending for KH BBS MX says that all the seeds for his plan had already been sown, or something along those lines, I've heard rumour that one of these was telling Maleficent about princesses of heart, does anyone know anything on the matter?

 

yeah, Maleficent even says it in the game like 3 times

 

Yeah I had a feeling she did, do you know anything else about this though?

 

Well, he is an old man, he could've started "planting seeds" since his 40's for all we know. Most likely they will reveal his plans more in depth in KH3.

One of my theories (which may be proven wrong) is that Xehanort may have left a piece of himself inside of Ven. Remember that

Spoiler

Ven was Xehanort's apprentice before he met Eraquis. Perhaps a piece of him lives within Ven. They both wear the same colors...
In fact, Xehanort even said in the secret ending to Terra, "Know this...you are just one of many roads that I might choose to take. Trust me. I made certain of that."

 

There are many things Xehanort can refer to about the seeds.

When he was in control of Terra and had forgotten all but the name, it's never explictly said who was in control of the body, maybe Xehanort's piece saw through his Heartless and Nobody, there is also Riku to consider considering he was once Xehanort's puppet despite being controlled by the Heartless so this is sort of indirectly.

Then there's Kairi, Xehanort sent her through Radiant Garden's World Door and she ended up at the Islands thanks to Aqua's magic on her pendant.

There's also another issue, Sora defeated Xehanort's Heartless and Nobody as well as Org XIII's Nobodies, but what about their Heartlesses?

*Spoiler*

And maybe Xehahort knew about the Heartless and Nobodies before anyone else and knew when they were defeated, he'll return to his original form as Yen Sid learnt in KH Re: Coded.

 

Actually Xehnort did know about the Heartless, not sure about the Nobodies, because in the scene where Vanitas is created it shows Ven being surrounded by Neoshadows.
