Dear diary,

I have decided to build a city. It'll be underground and will replace the mine. There's enough resources there and with the large cave systems, hundreds of tunnels and the ravines cutting through the ground I don't have to do nearly as much digging.

I have already been clearing out tunnels and knocking through dividing walls to open them out and make them easier to explore, so it's not a great leap from that to digging out space for houses. I've also been filling the area with torches and haven't encountered any monsters within the lit areas - perhaps they dislike it? They only come out at night, so I guess they don't like light and the zombies and skeletons are definitely hurt by sunlight. This could work as long as I have enough torches, but with the amount of coal down here I don't think that's going to be a problem.

I think this could work.

Alex
