This command opens a guided conversation with beings you encounter in the
valley. They speak first, then offer a lettered menu of things you can
raise with them; type the letter to follow that thread, 'x' to step back,
'y' to return to the start, and 'z' to take your leave.
Not everyone will sit for it. 'greet' and 'ask' remain the main way to get
information from the people you meet, and nothing you need is locked
behind this command - a conversation tree is extra depth where someone
has a lot to say.
Usage: talk to <monster>
Example: talk to guard
See also: ask, greet
