Once a dedicated environmental scientist monitoring creek health, the Oracle was transformed when the first wave of contaminated runoff from upstream construction flooded their research station. The toxic exposure granted horrific prophetic abilities while corrupting their physical form into a living embodiment of industrial pollution. Now they read the contamination patterns like ancient runes, predicting creature emergence through the ebb and flow of chemical tides.

The Oracle's form constantly weeps industrial ooze that shifts color based on contamination levels, from sickly green for minor pollution to deep black for maximum toxicity. Their eyes have become clouded pools of chemical runoff that glow with bioluminescent bacteria, allowing them to see through supernatural fog and peer into the contaminated future. The ooze they secrete forms prophetic patterns on the ground that dissolve as each prediction comes to pass. Their presence intensifies the crosshatching fog effects, creating dramatic backlighting that silhouettes their corrupted form.

The Oracle serves as the creek ecosystem's contamination-based early warning system, appearing at water monitoring stations to provide cryptic prophecies about creature emergence timing and intensity. Their predictions manifest through ooze patterns that all players can interpret, making environmental intelligence equally available to everyone regardless of faction affiliation.
