Awesome. That is just what the woman wanted from him. Out come the essence potions, and she gets to feeding the node. It nibbles up the provided free essence in an almost happy manner. She seems to know just how much to feed it, too. She stops just before it reaches more essence than the node can handle, and backs off. The node stops nibbling on the both of them, just a bit, because it's too busy nibbling on the free essence to go through the work of taking it. It will instead happily get to processing as it nibbles.

The woman smiles at the node rather fondly, and then gets out a book of something and writes... something... in it. She marks the black dot signifying the node on her map with at set of symbols, and copies the symbols to the book. She notes another black dot on the map, and writes another entry with added symbols for that one, too.

It might be possible that the world doesn't need him. It seems to already have someone. But the someone probably won't mind sharing; there is an awful lot of world to save.
