13HRP – 0121 – Pulse Void Door is a massive stone doorway found deep within the catacombs beneath the Great Lost City of Albion. It stands near the ruins of an abandoned military research base, and therefore it has drawn significant attention from researchers. As a result, the Hollow Reality Project classifies it as one of its most mysterious gateways.

Structure and Function

The Pulse Void Door does not lead to a normal chamber. Instead, it appears to connect directly to the Void, an unknown dimension beyond conventional reality. Furthermore, the doorway emits slow pulses of golden light, which gradually move through the surrounding stone and then flow into a network of brass and silver pipes embedded in the cavern walls.

However, researchers do not yet understand the purpose of these pulses. For example, they may act as a power source, or alternatively, they could function as a communication signal. In addition, some theories suggest that the pulses indicate the doorway itself is alive.

Key Mechanism

A large stone keystone rests above the archway, and it displays symbols that no one has successfully translated so far. At the center of the doorway sits a single keyhole, which directly matches 13HRP – 0082 – Pulse Void Key.

Consequently, evidence suggests that the key and the doorway form a single system. Nevertheless, no team has activated the mechanism so far, and therefore its true function remains uncertain.

Observed Effects

Personnel report several unusual visual effects during observation. For instance, the light around the doorway bends in unnatural ways, and as a result, the entrance appears deeper than it should be when viewed from certain angles.

Moreover, long exposure causes spatial distortion and depth perception issues. In addition, some observers feel that the chamber shifts slightly, even though it remains physically unchanged.

Current Status

So far, no authorized expedition has entered the Void through the Pulse Void Door. The mechanism remains inactive, and meanwhile, researchers continue to monitor the site and prepare for future activation.

Until activation occurs, the destination beyond the doorway remains unknown. Therefore, it stands as one of the Hollow Reality Project’s greatest unsolved mysteries.
