Rudra no Hihou

Turn-based RPG where humanity's extinction arrives in 15 days. You control three characters across separate storylines—a soldier, a priestess, an archaeologist—each experiencing the same apocalyptic fortnight from different angles. Switch between scenarios freely; actions in one timeline affect the others. Leave a relic in one chapter, another character finds it days later in theirs. The magic system lets you construct spells from scratch using a custom word-based language rather than picking from a preset list. After completing all three arcs, a fourth scenario unlocks featuring a thief and unites everyone for the endgame. Setting draws from Indian folklore. It's structured like three novellas that intersect, then converge.
