The Topazial Rift

Great Topazial (dimensional) Rift
Danger: High to Very High
Inhabitants: Living Whirlpools, merfolk, cecaelia, dimensional trappers, a Kraken Caelia, various creatures from other worlds

Located approximately in the center of Topazial Sea, the Rift is a dimensionally hyperactive sub-zone comparable to Miragia Forest in its overall dimensional activity, though it covers a larger area. The actual appearance is normal enough, just another stretch of sea, until it's too late to turn back. The Rift is known as the absolute bane of seafaring navigation to Felaryan natives, for with many devices, even some magical ones, will often cease functioning. Furthermore, the weather is prone to changing dramatically, from calm seas to black storms, tidal waves, and aggressive whirlpools, in an alarmingly short period of time.

Strangely, the Rift only seems to connect to the seas and oceans of other worlds, meaning that the most common things to appear inside of it are sea vessels, aircraft, various sea creatures, and sometimes entire islands (though islands typically phase back out of Felarya rather quickly).

Despite the sheer potential danger of the sub-zone, there are wild claims that, similar to the Great Dimensional Gate of Ur-Sagol, it is possible to navigate to an entirely different world altogether if one wills strongly enough, or otherwise enters a random portal. This keeps a decent amount of traffic coming into the Rift from Felarya itself, though the effort is widely considered a mad and suicidal exploit.

There are many, both speculators and survivors, that believe the dimensional activity and fickle weather are two separate phenomenon, and
that a resident kraken caelia is to blame for the weather, merely taking advantage of the zone's dimensional qualities in order to play with what appears, and fill its immense stomach..

The Rift doesn't stay static in form. Its boundaries warp in shape, but the exact center is reliably stationary. Sometimes a navigational chart will tell you you're safe enough away from it, while it would unexpectedly reach out far in one direction, and the opposite side of the Rift will have no activity. Obviously, if you want to stay out of it for sure, give it a very wide berth.

It is worth noting that the deepest depths of the sea within the Rift are completely littered with artifacts from many different races over the eons. Though this now-junk covers the riches of the seafloor, the technologies that may be potentially recovered from the wreckages are likely to be worth fortunes themselves.

In essence, the Rift is kind of like the legends of the Bermuda Triangle or Devil's Sea on steroids. And is likely where the Triangle leads.

I'd imagine that all sorts of mayhem happens in the sub-zone's epicenter, from alien sea creatures entering Felarya en masse, to confused nautical battles suddenly interrupted by giant predators, and the most hardened and prepared pirates, smugglers and adventurers aiming for trans-dimensional voyages.

Unfortunately there would be quite a culling of new arrivals and would-be world-hopping ships due to the largest inhabitant- the activity of which is why the danger jumps to Critical at times. It would normally be High, simply because of the dangerous weather.

I know Topazial Sea already has fairly numerous sub-zones already, just an idea.

Oh, it's interesting

I think this is a nice one ^_^
We need to have a bit more animation on the seas of Felarya to break the monotony

Thank you

(Felarya? Monotonous? This... This is blasphemy!)

How can the Creator blaspheme?

As for the idea itself, I agree. It's very interesting.
