One clock within Chrona's temple is more embellished and elaborate than all the rest. That particular instrument continues its functioning for time immemorial. It must, for the consequences of its stopping would be apocalyptic. Without the mechanism keeping the time goddess in motion, time itself would stand still. It is clear, then, that none other than Chrona herself should have the power to stop it.
Chrona is the female variation of Chronos, the personification of time in Greek pre-Socratic philosophy and later literature.
