Holy butts I actually drew this place. :U So, I dunno how to actually start explaining, lol. I guess a good starting point would be its position on the planet. Um, somewhere in the ocean... It's somehow a floating landmass, like Angel Island; methinks it uses magnetism rather than some arcane power like the chaos emeralds.
The island floats at about 3,000 feet above the surface of the water, so nigh impossible to escape except by air transport. And since snakes can't fly, or even glide very well, this is their permanent residence. Not that they mind much of course, the place is practically tailor made for them. The temperature of the whole island is all 'round the same, roughly 80 degrees. The mountain ridge makes the landmass concave, reaching up to around 10,000 feet from the low lands, and yes, snakes even live on the inside of the ridge itself.
I know the borders of the sections look pretty pronounced, but there's actually no real borders between the sections. They meld together fairly well, and which some borders make viable habitats in themselves, such as the conjunction between the desert section and the forest section making somewhat of a savannah-like plane, albeit marginally small. There's a rainforest sub-section in the forest section; that's what the dark patch is. And yes, those are little oasis spots in the desert section.
Now you might think what of the city section; snakes don't like those as much, right? Well this city isn't as high tech as the many ones of the mainland; this city only uses electricity for inside homes and buildings, but the streets are all lit with gas lanturns, and the electricity used for inside buildings is no brighter than incandescent, thus this island is probably the least polution-ridden landmass. Clear nights offer very starry skies here. Electricity is made via wind turbines, which is generally an easy flow thanks to the mountain ridge steadying air currents. Being the toned down city as it is, snakes can also live in the city as well.
I said the temperature is generally the same all 'round, but it's a little 'tilted' considering the East and West sections. The desert section is warmer than the rest, and the aquatic section is cooler than the rest, which does affect the North and South sections. The rainforest is closer to the aquatic section, while the marsh section closer to the aquatic section is more swamp-like than the other side, due to the humidity. And the desert section pretty much sucks up excess moisture in the air, which keeps the whole area balanced.
And yes, there are animals on the island to suffice as food for the snakes and the city dwelling mobians. The island can be visited by aerial transit, either by people wanting to simply visit the island, or bringing in new snakes. And if anyone's wondering, the snakes are mobian as well. Nagas also share the island. Um... These sentences are getting cheesy... Anyway, I also said in another picture of mine somewhere, I think, that the serpents are civilized, so they aren't just predatory all the time. They can be conversed with, but they aren't savvy with mainland stuff, so pretty much any big events that happened where everything else goes on, they won't know about it. Methinks they'd also be illiterate.
I may put up the size of the island eventually, it's just kind of hard to put numbers to an imaginary place. .3. And an interesting thing about this island is that there are 16 special nagas living within it that serve as the guardians of the island. Long ago when the island was created (well I say that, it was found in its spot and turned into a levitating island and reconfigured into its current habitual organization, funnily enough by the nagas), those nagas set up posts at points along the mountain ridge, and they possess a unified power that they use to protect the island from natural disasters. How it works is basically the first naga to activate their corresponding post, causes the post to send a bright beam of light shooting across the island, which then signals the other nagas to activate their posts, and the light beams cross together right over the city section, before fanning out and creating an energy barrier over the landmass. The 16 guardian nagas are all over 700 years old, and they all live near their posts; four in each section, excluding the city.
The main reason for this island's purpose was to give giant mobian snakes a home away from the mainland, being as snakes in general can be dangerous creatures, and making them bigger, stronger, and smarter wasn't boding well for life in the bigger areas. But people didn't want to just kill them off, that wouldn't be fair. Mobian snakes do still appear on the mainland, and are only left alone if they can stand well for mainland life.
