The Infested Baneling Nest is a grotesque, organic structure resembling a pulsating sac covered in thick, veiny membranes and chitinous plates. Its surface is a mix of dark purples and greens, with glowing green pustules that emit a faint bioluminescent light. The nest has a asymmetrical, bulbous shape with several orifice-like openings that periodically release Banelings, surrounded by smaller tendrils that twitch and writhe as if alive.
