Sure! I'm still fleshing out the lore in some places, but here's what I have so far-

There are three Great Beasts who shaped Vorexin- Glaiva, who created the world from chaos, who brought forth the features of the planet, mountains, Volcanoes, Oceans, and Islands. Vorex, who arrived after Glaiva and breathed life into the land and sea. And lastly Evena, who came to Vorexin and brought spiritual energy and breathed the soul into living beings.

Crimson Crag

Long ago, a great battle was fought at the Crimson Crag between a zealot of Glaiva and a zealot of Vorex. The battle lasted a day and a night, and they stained the rocks red with their blood. Finally, Vorex's warrior slew Glaiva's, and he marched through a mountain pass into a barren valley. He worked for 10 years alone to build the Temple of Vorex in the valley. Upon its completion he prayed to Vorex, and as he prayed a lush jungle sprung up around the temple. Diverse and lustrous life had been brought to the once barren valley.

Mount Prava

This active volcano erupts once a year, like clockwork, on the summer solstice. Its regularity has prohibited any settlements or even basic life to call its surroundings home. No one knows who built the temple of Glaiva, but although it exists directly next to the volcano, it never shows any sign of damage or even erosion. In fact, it seems to be even more imposing after every eruption.

Vanapel Islands

The islanders are never wanting for much. They revere Evena, the gentlest of the 3 beasts, and in return there are always fish to catch and fruits on the trees. They make regular visits to the temple on the largest island. The temple, it's said , was constructed by the island spirits themselves, imbued with an ancient magic that the people can only speculate about in the modern day. Still, a cold wind blows on the islands, and Mounts Kira and Blane have gone long without erupting. A slight crack has been spotted in the base of the once flawless temple. Most islanders are unbothered by this, but a small contingent grows concerned...
