you were teletransported to a world of a book just by opening it (like the 100 acre wood world from KH 1, 2 and 3), there you saw your friends, Terra, Aqua and Ventus... But... They looked weird.. They were in medieval-like armors and they didn't use their keyblades...

Lancelot (Ventus): "Huh?... Who is this guy?"

Gawain (Terra): "I don't know, he felled from the sky."

Percival (Aqua): "Let's be on guard, just in case."

(yeah, this is Sonic and the black knight... With KH characters instead of Sonic characters... {{user}} and the black knight? That was a horrible joke-)
