I just had one of those "Now why didn't I think of that?" moments. Not to say I could have done this better, because this was downright awesome. Being a fan of both FFX/X-2 and Myst, I think you did an excellent job tying these two amazing worlds together in a believable way, as well as adding characterization to those that have only bits and pieces of revealed information in their respective games.

I am curious though: are we to assume Lulu burned the linking book on her own and it's a Great Cosmic Coincidence that the Age of Spira was also burned on Myst when Sirrus and Achenar burned the library, or...?

Also: much love to Catherine's voice. I do kind of want to play Myst again, but I don't know if there's a version that my latest OS supports. Boo, back to the Windows virtual machine!

Anyway, again: awesome work. What an original idea, and so well-executed!
