Turn 2
Two thousand years, have passed. In the blink of an eye, too. The mountain is silent as ever.
Urn commands the sea, the land, and the sky, and each of them tunnel inside the island as the force of the insides relishes its new realm. What comes is a expansive series of caves and caverns that are connected to the surface by numerous cenotes that are fed by subterranean rivers, which range from the largest tree to the smallest bird in lenght and width.
Yithr softens an islet they see appopriate, molding its material along with the adjacent shore, to make an very shallow coast that stretches into the ocean. Hills of sand and pebbles roll just beneath the coastal waters, and though its barren for now, Yithr, is sure that won't last.
And yes, it doesn't lasts. Life, aided by the combined influences of Fin and Cryax, make this place home. Soon, from the sea and the waves, a freshly new marsh is formed by a layer of moss. These mosses grow uncontested, and soon create a fuzzy squishy grassland that one can sink their feet in and into the sea. Grubs colonise these new pastures to graze, and predatory land penguins follow them from the adjacent coasts as well.
But as Yithr was sclupting their marsh, the rumble and sound they make attracts Fin, who decides that what was taken, must be added back. So they move towards another islet, but expand it throught the ocean instead, until it touches the main island, creating a saltwater-soaked flat of dirt and mud that gradually fades into the ocean.
Coconuts quickly follow the moisture as they grow downhill towards the new swamp, first getting impeded by the increasing amounts of saltwater, but then quickly adapting in the way of the mangrove, growing large, salt resistant roots, some of which reach to the surface to breathe. And as the wind hits them, they whistle a tune from their leaves, indiscrete and unfocused.
Yes, the trees sing as the wind hits them. Grubs whistle from their many spiracles, tunes as diverse as their species. The birds obviously sing as well, using it to communicate, to intimidate, to attract, to coordinate. By this, the birds and seals outbest eachother throught the centuries, and the grubs and beetles alert eachother to food and danger.
This new gift of song is of Ix, and they enjoy the melodies change their notes and ryhtms as the aura of change shifts them evermore.
In where the gods live, however, Cryax seeks to preserve themselves from dangers. Is this even really necessary? Can Cryax even be harmed in a way that matters? They did not know, but that doesn't stops them from lacing their being with cognitohazards which inspire mental pain on anyone that may try to see them without their permission.
A swarm of pigeons purr in unison, having brought with them some raspberries, via their intestines. These new woody vine plants now cover the palms all over the forests of the island, which have covered all corners of it ever since Urn created their cenotes and have also indirectly caused the formation of several aquifers that have since sprung up to form rivers and streams all across the island.
The island grows. All is well. For now.
You guys want an alien island huh? Alright, that's what you will get.
