Fermentation release energy that does not require which gas

The biological purpose of alcoholic fermentation is to provide anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen from glucose. In the process, the yeasts obtain energy by dissociating glucose molecules and generate alcohol and co2 as wastes.

moon-letters were a method of writing invented by the dwarves. moon-letters were ordinary runes, but written in such a way that they could only be read when the light of the moon shone behind the writing. some moon-letters could be read by any moonlight, but it was possible to make the writing even more secret. more sophisticated moon-letters could only be read by the light of the same shape of moon, or at the same time of year, as when they were written. hope this !
