Guildmaster

This Paleoterraria NPC acts the same as the guide does in the base game. He gives you hints as to how to attract the other NPCs to your town. He also gives hints as to what you can craft with the materials you have in your inventory as long as you have the appropriate crafting area in your inventory as well, and the correct materials are accessible in your world with the current mode modifiers(such as pre-hard mode, before/after certain bosses, hard mode, expert mode). Finally, you can ask him about the different ways to strengthen NPCs.
