This is not Idaia's closet.
It's something weird.
That could be either a really good thing or a really bad thing.
She probably wasn't going to succeed at what she needed to succeed at anyway; worth the gamble.
She steps inside.
It doesn't seem that weird by Materian standards in basic concept, just in allowing somebody to leave the anti-science planar neighborhood.
Oh wow, yeah, just lousy with all kinds of ways to get things done.
I'm not sure it'd necessarily be nice - Materia's not-nice in other ways besides the science thing - but it would be, I want to say rich.
Not very. We should also find a way to leave them something nice in exchange for their library. And have Fëanáro learn to write their language and send them an apology.
I wasn't imagining we'd steal an entire world's only library, either.
I don't think I remembered to ask how long it took to invent writing without outside inspiration.
