The lost boy can be teleported home in a shower of rainbow sparkles. The Esmaarlan vampire - he can't do much for. (There's an entire kind of magic widely regarded as a disease? Maybe he'll think of something later.) The member of the dragon council can have a swirl-patterned note that says 'miracle' in Draconic and flutters its little paper wings to hover at eye level. (His human body mumbles that word, too.) The people in Oridaan can keep on wanting. The girl who wants to thank him can have a murmured, you're welcome. The student who wants a bigger channeling capacity - what's a channeling capacity? Come back to it later.

The sick light - can lights not heal lights? Can lights not heal themselves? This is clearly contrary to the point of lights and it can just stop. He provides the sick one, and any other light who happens to be sick or injured and not otherwise occupied, with a written suggestion that they try lighting up. He can't do much for book sales, but he drops a little luck-blessing on it; and the old man in Tava isn't even worth answering in the negative, which he reserves only for prayers that really tick him off.

Now: channeling capacity?
