Driftglobe

A driftglobe was a small glass orb that magically floated in the air and emitted light.

Description
A driftglobe was a small sphere of thick glass, that weighed about one pound (0.45 kg).

Powers
The most common driftglobes had three basic magical effects. They glowed with bright light, equal to a torch, as per the cantrip light, on command. They could also glow with the brightness of full daylight, as per the spell daylight for an hour at a time, though use of this ability was limited to a number of charges before being used up. Lastly, the driftglobe floated in the air, as per the magical spell levitate. A driftglobe could also follow a creature that touched it, similar to the disk created by Tenser's floating disk.

History
Driftglobes date back at least to the time of Cormanthyr at its height and were seen lighting up the night in Myth Drannor. The arcanist Congenio Ioun created the first light-emitting ioun stones sometime in the age of Netheril but these were personal items that remained near their owner. Driftglobes could be found in use across the modern Realms, as well as in dungeons and ruins.

Creation
Driftglobes were quite easy to make, and the process was well known. A caster needed little more than a glass globe and the ability to cast daylight and Tenser's floating disk.
