Could essence be added to the list of gnome merchant wares?

Essence is for offering... You can't--oh wait yes you can (buy essence any other way). I guess I'm not sure I see much of a need to be able to buy or sell essence to gnomes.

Being able to offer dust has been suggested and approved. Purchasing grey essence, the sort you use in a nexus, is a novel idea which should be considered.

Grey? I thought there were only four flavors. And maybe we should use 'essence bits' to differentiate from 'godessence' or maybe 'gessence' and 'pessence' or 'nessence' (god, power, nexus). But yeah, purchasing p/nessence would be kinda cool and provide a less-griefable way of getting the necessary essence to raise organizational smobs.

Five flavours. The fifth is the un-converted state.

I don't think I've ever seen the un-converted type. Where does it come from?

Light essence (Celestia), silver essence (Serenwilde), dark essence (Magnagora), shadowy essence (Glomdoring).

The fifth is gray essence. We can get this by killing angels and demons and placing their corpses in the Well of Souls.
