Fairly straightforward suggestion regarding holes:
|“||...In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit-hole, and that means comfort...||”|
Although the holes mentioned in this quote were clearly intended to provide contrast to Hobbit holes, it shows us that such holes as these did exist in Middle Earth, and were evidently fairly common. Therefore, I suggest they be added to the mod. There will be two types of holes, wet holes, and dry holes. Both will vary in size from a one to four block three dimensional radius. In the bottom of wet holes, there will be water, in the bottom of dry holes sand. They will spawn most commonly in the shire, but also in other, similarly built biomes, such as Eriador and Gondor.
Feedback and constructive criticism are welcome. Like always, if you have something you would like to add, I would happily do it for you under your name!
