Guide

The Guide is the first NPC that you encounter, and spawns right away with a new world. He provides tips that are mainly for new players to learn the basics of the game. The Guide also provides information on what you can craft out of any item, just by showing it to him. Unlike other NPCs, he does not need a house, but will move into the first one built, which will often be yours. You may want to build two houses, first one for the guide, second one for yourself. If killed, the guide won't respawn until you make a house for him to inhabit.

The Guide can die. He will respawn in either your house or another vacant house that is correctly built for an NPC. After the Guide has said everything he will repeat them again. As most players know that he will take the first available home, many find him annoying, though no longer pointless as he now tells you crafting recipes.
