North of Leyawiin on the west bank of the river, there is a cave called Reedstand Cave. A very little bit northwest of this cave is an old-looking dock. There is a small sheltered portion of this dock on which I have placed four doors in a square. Open any of these and you will see a sewer entrance. Go in and you will come up in a giant swampy house. Keep in mind that this is my first ever mod made public, and that the mod isn't finished, so don't expect TOO much. Also, let me know if there are any problems with download/installation... Though I'm not sure how much help I can be.

Version History:
v0.65- not as much as I would have liked has been added because I rushed to release this version out of excitement. I have elevated a single mushroom that was too low down in the water, I've added one piece of furniture upstairs (lol), and best of all, I've added mice: that includes the enemy, a more realistic way of getting up the stairs, and I had a New sickness known as the Swamp Plague in the works, but I couldn't get the script right :(. --Sorry, it got uploaded twice, only download it once.

v0.6- finished mushrooms, still nothing upstairs.

v0.5- made house, placed a few mushrooms.

Sad, Sad Problem:
My mother, after I specifically told her not to turn off my computer because of this mod, has done just that. I can't make any more updates for the mod :'(. You can still download what I have. It's not much, but I find swimming through a foggy giant mushroom forest very peaceful. Sorry, everyone... but I think I have an idea for a new house, which I'll get right on, look out for it :).

Edit:
A very helpful person on the forums has told me how to continue to edit a mod that has been exited out of. I can now proceed with developing my idea.
