Kalem's Comet

Kalem's Comet is an astronomical phenomenon where a bright purple comet flies across the sky. It is associated with fey magic, and when the comet is visible on the material plane fey magic there is empowered and more fey crossings are opened. The comet does not occur on any regular interval, but in the nights preceding its appearance a purple glow can be seen on the horizon.

The last known appearance of the comet was on 18 Frostfall 818 GE.
