The Shattering of the Arcanum Veil is a pivotal event in the universe's history, marking the moment when the Veil's intense arcane energy could no longer be contained. Over millennia, the Veil grew by absorbing floating arcane energies, becoming increasingly powerful. One day, the accumulated energy reached a critical point. Under immense pressure and heat, the Veil shattered in a massive explosion, releasing an overwhelming burst of arcane energy.

This explosion sent supercharged magical crystals flying through the cosmos at unimaginable speeds. These crystals ranged in size from tiny pebbles to comet-sized structures, each imbued with the concentrated arcane power of the Arcanum Veil. As they traveled through the empty cosmos, they encountered barren, rocky planets.

The smaller crystals burned up upon entering planetary atmospheres, their magic reacting with the atmospheric elements to create new, life-sustaining environments. The larger comet-sized crystals struck the planets' surfaces, where their arcane energy fused with the soil, sparking the genesis of life. This infusion of magical energy led to the emergence of diverse forms of life, from microorganisms to complex plant life and even sentient beings on some worlds.

The Shattering of the Arcanum Veil thus transformed countless barren planets into vibrant worlds teeming with life. It marked the beginning of life in the universe, with the magical crystals seeding life across vast distances. The legacy of the Shattering is evident in the widespread presence of magic and the diversity of life forms that populate the universe today.

Even though the Veil shattered, its influence persists. The remaining fragments of the Arcanum Veil continue to emit arcane energy, maintaining a mystical connection with magic users and inspiring various religious and cultural practices. The Shattering of the Arcanum Veil is remembered as a cataclysmic yet life-giving event, a moment of profound transformation in the history of the cosmos.
