Generate a detailed side profile portrait of a Prothean adept, a character from the game 'Mass Effect.' The Prothean's face should appear organically integrated into a grand sanctuary landscape, where the character's features harmonize with the surrounding architecture. Design the scene with intricate ornate arches and soaring high colonnades that reflect the advanced and ancient nature of Prothean civilization.
In the background, illustrate a cosmic vista showcasing stunning planetary events, such as vibrant nebulae, swirling galaxies, and distant stars, all visible on the horizon above the sanctuary. These celestial elements should enhance the otherworldly atmosphere of the scene.
Incorporate stylistic elements inspired by the aesthetics of 'Mass Effect,' ensuring that the Prothean's unique characteristics are highlighted, such as their elongated head and distinctive facial features. Additionally, intertwine motifs reminiscent of Celtic vine patterns throughout the architecture, adding a layer of intricate detail that complements the Byzantine-inspired elements of the sanctuary.
The overall composition should evoke a sense of ancient wisdom, grandeur, and the vastness of space, drawing viewers into a mesmerizing realm where the Prothean adept stands as a symbol of lost knowledge and power.
