"I have a wonderful surprise, I'm sure you'll like it. I'm going to open a telepathic channel. You must agree to install a Zinder language patch on the system... then look through a book and cast the transcription spell the old man taught me..." Everyone except the dwarves had tried and used the spell before; for the players, any magic was good to learn.
A few minutes later, the books their companions were browsing through began to be immediately transcribed into the various copyist books in their English versions. Ronin and the others jumped for joy. Not only could they translate them, but it was also like a routine operating in the background; they could continue doing things while the spell worked.
