Window 3, 'the Slime Marsh': Color-Change Correlation Reinforced Again — 'the Watcher' Stays Back From the Boundary

The TDA's Dimensional Survey Division told this paper on the 9th that an opening of Window 3, 'the Slime Marsh,' lasting roughly 95 minutes on the 8th, again showed the previously reported weak correlation between color changes in 'the Watcher' — the individual, officially numbered 88-C, that repeatedly appears before the window — and lighting and movement on the observation-room side. No approach to the boundary glass has been confirmed since the closest-ever approach on September 18, and the division maintains that recent observations fall 'within the usual range.'

Window 3, "the Slime Marsh," opened for roughly 95 minutes on the afternoon of the 8th. As previously reported, the window had settled into a quiet stretch of observation with nothing notable since its September 24 opening, but the Survey Division said several individuals were observed again this time, including the previously reported "Watcher," officially numbered 88-C. The Watcher again showed slight color changes that tracked the intensity of lighting and the movement of window keepers on the observation-room side.

This correlation between color change and lighting or movement was first confirmed statistically on September 11, and the division has repeated from the start that it "does not prove causation, nor does it constitute evidence of being watched." An official told this paper on the 9th, "The more observations we accumulate, the more stably the correlation itself holds up. But its strength remains rated 'weak,' and we still have no additional basis, this time either, for judging whether this is an intentional response or simply a physiological reaction to environmental change."

As previously reported, the Watcher approached closer to the boundary glass than ever before during an opening late on the night of September 18, its color fading to near-colorlessness for several seconds before flickering faintly. In the following opening on the 24th, only several individuals were observed with no approach, and this time, on the 8th, the Watcher again kept a comfortable distance from the window. The division maintains its position that "one more piece of evidence has accumulated, again, for treating the September 18 approach as an exception."

Window 3's observation data has already been added to the agenda for the previously reported outside-experts review panel, chaired by Etsuko Kajiura. The data is also shared under the 7th International Joint Study, co-chaired by Hinokuni and the Hindu Federation, where some unofficial opinion holds that it "cannot be ignored when considering the possibility of communication." The Survey Division, however, continues to call the start of any international joint analysis "premature," and today's observation results are expected to be added to the panel's materials as well.

    Window 3's 'Slime Marsh': A First Statistical Link in the Color Changes — Still No Proof of Awareness

    The Dimensional Survey Division said on the 11th that it has found a slight statistical link between the timing of color changes in one recurring individual near Stable Window 3, 'the Slime Marsh,' in western Tama, and lighting or movement on the observation-room side. The creature has long been rumored to be 'watching' visitors, but officials repeatedly stressed that the finding is not evidence of any exchange.

    Window 3's 'Slime Marsh': 'the Watcher' Touches the Glass for the First Time — For a Moment, Its Color Vanished

    At Stable Window 3, 'the Slime Marsh' (Lineage 88), in the Inagi valley of West Tama, an individual known to window keepers as 'the Watcher' — which has repeatedly appeared before the window — was observed late on the 18th approaching close enough to touch the boundary glass directly for the first time since the window came into service. At the moment of contact, its color faded to near-colorlessness for several seconds before flickering rapidly. The Dimensional Survey Division maintains this is no proof the creature is 'looking back,' but says the observation is without precedent in its records.

    Stable Window 3, 'the Slime Marsh' (Lineage 88), in the Inagi valley of West Tama, opened for about 70 minutes on the afternoon of the 24th. Six days after the previously reported incident on the night of the 18th, when the individual known as 'the Sentinel' (official number 88-C) approached closer to the boundary glass than ever before, its body briefly turning colorless and then flickering, the individual was again observed today but kept its usual distance from the glass. The Dimensional Survey Division described it as 'a quiet observation' and reaffirmed its stance of waiting for November's outside expert panel.
