The Wheel of Ages was a massive stone disc in Darujhistan's Majesty Hall that named each year in accordance with its mysterious moving mechanisms. The wheel spun slowly all year and would align with the new year precisely at dawn, traditionally the beginning of the New Year celebrations. The wheel had been gifted to the city by the Jhag Icarium over a millennia ago.
Kalam Mekhar recalled seeing a device called the Circle of Seasons within a temple in Darujhistan. Said to be created by Icarium, it was unclear whether this referred to the construction found within Majesty Hall.
