Here's a little story, as possible background for how this addition would come about. Recently, the community of Stardew valley has been a little disgruntled. Recently, the sewer overflowed and made the surrounding area almost deplorable until they cleaned it up, in short order. But that's not the problem. Several of the residents have noticed the local wildlife inexplicably disappearing, and some of it was just gone right after the spillage. A few of the more nature-savvy residents get together (you're invited, of course) and come to the conclusion that the wildlife was driven off by the severe pollution the spillage caused, even if it was taken care of quickly. Without the wildlife, the ecosystem will inevitably be thrown right out of whack. Robin, who attended the meeting because her husband was worried about the issue, suggests they build a sanctuary. At first, Lewis rolls his eyes, like 'another drive for business, huh?' before he realizes she wasn't joking. Seriously considering the option, the gathered residents come to the conclusion that it would be a great idea to build a sanctuary to attract the wildlife back into the valley. The only problem is that they have nowhere to put it. Here's where a choice comes in: if the player so chooses, they can have the sanctuary put in that little area to the right of the farm and left of the town, or bring up 'general effort' (read: don't build it, instead making a local law to be friendlier to the environment and letting the wildlife come back over time, which doesn't do anything gameplay-wise). As a mercy, the player can later craft a 'letter' and gift it to Lewis, which will proc the question to come up again, if the player changes their mind after saying no. By saying 'yes', an event will take place over four days, in which Robin, Clint, and Demetrius will be working in a small area, accessed via a path on the right border of your farm. If you help out each day, completion will be reduced to three days, instead of four (that part could be a little tricky, so maybe not. I don't know how coding works, so it's a guess). Once it's done, Demetrius will give you his thanks (+Heart with him, Clint, and Robin for helping out) and let you know that he's more than willing to set up more diverse 'attractions' for wildlife. The 'buildings' are in fixed positions, for the most part; I.E., there are a few 'hotspots' for each building, so it's not free placement. At first, all you'll have is a 'Leafy' tree at the center of a grassy grove. It attracts birds. Talking to Demetrius will allow you to upgrade (or learn how to, since you're the farmer here) it to a 'Greatwood' tree (thicker trunk, generally bigger), then to an 'Elderwood' (same upgrade, except it additionally looks older). Talking to Leah will let you build a 'Carefully Constructed Tree', which is geared towards squirrels. Squirrels give you nuts. You can upgrade it to 'Twirling Tree', then to 'Wooden Maze' (which just makes them look more complex/add more holes). Talking to Linus will let you build a 'Grassy Field', which attracts foxes who regularly give you unique (or out-of-season) berries. It can then be upgraded to a 'Fruitful Meadow', then 'Harvester's Home'. Talking to the Dwarf will let you build a special underground area, which attracts moles that regularly dig up minerals and whatnot. At first, it's a 'Basic Burrow', then a 'Digger's Dugout', and finally a 'Natural Digsite'. Once each of the top levels have been achieved, the Wizard will send you a letter. It informs you that he commend you for your dedication to the wildlife, and asks that you come see him for something. Talking to him allows you to upgrade each area once more each. The base cost is 25 Void and Solar essence, plus the additional- Tree - Duck Feather, upgrading it to an Ancient Tree. C. Tree - Cedar Resin, upgrading it to a Branching Labyrinth. Field - Pomegranate, upgrading it to a Dreamscape. Burrow - Rabbit's Foot, upgrading it to a Miner's Paradise. Once this has been done and the upgrades have been completed, each of the four animals - a bird, a squirrel, a fox, and a mole - will be sitting in a circle, and at the center, a Stardrop fruit. Once you eat it, they'll scatter back to their own little homes, and you'll have the satisfaction of having built one of the most impressive and magical sanctuaries in the country - nay, in the entire world! I think if this was turned into an update, it would deserve a spot as DLC, considering the massive scope of the project. What do you guys think?
