Mysteria is alive:

Mysteria is alive: forests, rivers, lakes, mountains, and deserts cover its vast world. Sky cities, shadowy caverns, sentient groves, and aeries dot the landscape. People are born of wood, wind, storm, and fire. At its core lies one truth: Everything in Mysteria is connected. As the moon begins its long ascent, the Silver Hours unfurl across the land, drawing a cool, luminous veil over the waking world, "Infinergy-Aera" courses through everything. Mysteria, tidally locked, keeps one hemisphere always facing its sun, the other in perpetual night. The sunlit side teems with life; the dark side, Veltharun, remains unknown. On the bright side of Mysteria, the sun never sets, so true darkness never comes. Still, people talk about 'night', not because the sun sets, but because the moon rises. When the moon is up, its pale light shines through the mists, creating the Silver Hours. This period is Mysteria's version of night. Across the land, cultures use these hours for rest, rituals, and meditation, seeing the moon's watch as a quiet balance to the day. Ley‑lines run like a vast circulatory system beneath the land, channeling raw Infinergy-Aera from the planet's molten heart up to the surface. This "Aera" can be seen and felt in the weather, plant growth, and Aeratic surges. From these currents, Mysteria's greatest guardians emerge: the Elder Trees. Scattered across the land, Elder Trees are not just flora. They shape the weather, protect life, and guide civilizations. Of these, five are known as Great Elder Trees. Each one is a ley‑anchor whose roots and branches guide and mold the balance of an entire realm. But even the Elder Trees cannot dream forever.
