After Adarin and Isabella depart, Edarial gets back to juggling projects. Unsurprisingly, Iobel is a large help in this. Once she gets a handle on all of the things involved with being a monarch, he can not constantly be doing that alone. He still helps, he's still there doing monarch things and fixing the country, but now he's got a bit more free time to devote to other things.
Accordingly, there's a project he picks back up that he was only tinkering with before his marriage. He'd like to reinvent the fountain that heals familiars, have there be others in strategic locations, so that spellbinders don't need to rush to the capitol to avoid being unmade. Progress on the project's always been slow, there's a reason that it hasn't just been reinvented immediately after the spell charts were lost, but he's got some very good reasons to work on it with a near-obsessive zeal.
One day, to his utter surprise, when he goes to find another portion of the spell-chart to complete, he can't find it. He stares at the chart, stunned. Then he starts checking his work. It takes him a few days to finish the corrections.
Then he's done. He's remade a revolutionary spell chart.
He picks up the huge spell chart, does his best to fold it down to a reasonable travel size, and then heads off to show the nearest spell binder - Iobel.
