The Astral Spike Core is a surreal, otherworldly artifact with a central crystalline structure that emits a faint, pulsating glow. Its form is angular and geometric, resembling a shard of dark, opaque crystal with sharp, irregular edges that seem to fracture light. The surface is smooth yet etched with faint, glowing runes that pulse in sync with the core's light, suggesting an ancient, unknown power. The core is suspended in a minimalist, metallic frame that contrasts with its organic, chaotic energy, embodying the game's blend of brutalist architecture and surreal elements.
