This project is dead and no more. Feel free to complete this if you want according to your own vision. I am not ever going to finish the project. I am starting a new project that much better matches the original vision for this map. I have spent many many hours making a custom terrain and have restarted from the ground up. At this moment in time, I am not sure when it will release, but I can tell you that you will soon be able to meet the old man once more and fight some raiders in Realm of Beturune: Rebirth! Currently in development now.
Realm of Beturune: Generations is an open-world RPG adventure map. In this map, you will fight mobs, solve puzzles, and explore a beautifully crafted open world. Keep in mind that this map is a work in progress and more stuff will be added every update!

Explaining the end of this project and the announcement of Realm of Beturune: Rebirth.
Sorry if I got something wrong I speak Spanish
But I also hook it up to another block that tests for the player within a certain radius
1) Rather than using buttons or pressure plates use /execute @a ~ ~ ~ detect (insert block) ~ ~-2 ~ (insert command. That way, certain actions can occur naturally without the player having to step on a pressure plate to summon mobs or pressing buttons to talk.
2) do /gamerule sendcommandblockfeedback false. To prevent any text from command blocks to appear in chat.
3) instead of putting the item you need in a chest for the NPC. Use what I said in advice 1, but make it so it detects whether you have that item or not. If you have it, make it so when they're close it'll remove the item from their inventory and use /give to give them the item.
