Vanyel practices his magic.
Melody has been attempting diagnostics with Savil and Shavri, and they think a big chunk of the problem is that his mind got very rusty during the month he was unconscious and the ensuing months when his channels were too fragile to risk using his Gifts at all. So he's practicing. A lot.
After a few weeks of sustained practice sessions in Savil's Work Room, she offers to take him to the Web-room. He definitely doesn't have the control back for distance casting, yet, he can barely manage a wobbly shield in front of his own face, but it'll let him observe and remember what motions he would be doing.
(Also it's less boring for her.)
So he sits on the stone bench in the Web-focus room, in front of the enormous crystal focus that represents the physical core of the Web and the Heartstone that feeds it, and watches Savil with his still-kind-of-blurry mage-sight.
