Cold Sun

The Cold Sun is a completely cold stellar remnant the Mantle orbits. Its presence can only be detected by the naked eye via the occlusion of the rare star on the sky.

The Cold Sun emits a radiation that coldside flora thrives on, and with a special process, it can be used to activate Embers. This radiation is also emitted by galvanized Embers, the Petrov Rift, and Objects of Power, and has observable adverse effects on the health of those exposed to it for too long, however, it isn't a problem that commonly crops up due to the rarity of such long exposure.
