well since anything I could think of has already been say I can't really add much, though where the cube is it is mostly hidden in a deep place only few or none can find it, ether that or it is under everyone's noses which is why it can not be found, no body ever looks under their own nose it a nature blindspot, but this is only my reasoning and my reasoning is sometimes flawed, and on the Meeting the Shades, Khalazdad's Mission topic there is a small part about when khalazdad and a few others were being pulled into necrovion of being change into glowing shade like creatures and the same is in the Story of the Knator Commander in Yami no Sakura's Legend Collection,when the shades near the cube, I of couse have no idea what this means but you all are smarter then me, so you should be able to reason it out better and no body has bought it up again yet so any thoughts
