kthonica is a multi-day darkpsy and psycore gathering held at a secret riverside location in northern greece, with the exact coordinates shared only with ticket holders in the days before the event opens. the gathering runs across four nights with full on-site camping and a musical program spanning dark psy, psycore, experimental, ritual ambient, and drone and healing frequencies.

the programming is structured as a descent arc, moving through invocation and intensity toward integration, with ritual opening and closing moments anchoring the schedule. sound system setup and stage design are treated as part of the overall spatial approach, and the event operates under strict community codes around respect for people, land, and sound.
