CHTHONIC is an editorial project on re-materializations of the worlds we inhabit. It summons perceptions and records from multiple points within post-colonial, post-socialist, and post-conflict terrains, while searching for signals of post-digital and post-capitalist futures via particular countercultural practices and positions. By collating multifarious documents of site-specific dynamics, it listens for resonance underneath seemingly unrelated histories and horizons. The framework that holds them together is capsulized in the titular χθών [khthṓn], interpreted as an interlinked matrix of fecund underworlds that are there to revisit, reconsider, reconstruct, reinhabit, and repossess.
