Location from Defiance of the Fall by TheFirstDefier
A System-created challenge tower with floors of increasing difficulty and escalating rewards. A proving ground where cultivators from across the multiverse compete and are ranked.
The Tower of Eternity is one of the System's great proving grounds, open to cultivators below certain power thresholds. Each floor presents a unique challenge — combat, survival, puzzle-solving, or Dao comprehension. Rankings are multiverse-wide, and high placement draws attention from powerful factions seeking recruits. Zac's performances here have been both spectacular and controversial, drawing attention he'd rather avoid. The Tower is also where he first encountered Iz Tayn.
A colossal spire that seems to pierce reality itself, visible from multiple dimensions simultaneously. Each floor is a self-contained world — arenas, puzzle realms, survival zones, and battlegrounds. The architecture is pristine System-construct, all perfect angles and humming energy conduits. Waiting areas between floors resemble luxurious lounges where challengers can observe others' attempts.
