Description

"Aetherbound Echoes are unstable fragments of memory and energy, born from the pulses of the ancient Aether Anchor. They appear as flickering humanoid silhouettes of light, partially solid and constantly jittering, as if struggling to exist in both this world and the past. Their forms phase through walls and obstacles, striking with bursts of force or electrical energy. When damaged, they can temporarily vanish and reform, continuing their relentless pursuit of anyone who disturbs the anchor. Witnesses describe an eerie, pulsing heartbeat echoing from them, and the very air seems to hum with unstable magic wherever they appear."
