Siliph

The Siliph is a layer of clouds that divides Eolia and Tartarus and exists since the 3rd Sinneswald.

It was created from the gases that volcanoes and other phenomena in Tartarus released and concentrated in the lower parts of the atmosphere, thus separating the two realms.

The Siliph is several tens of kilometers wide and is composed mainly by a mixture of water and powerful acids iable to destroy a steel-armoured airship in matter of minutes. Also, behind the fluffy appearence of this infinite sea of clouds, a storm as old as Eolia and with the power of thousands of nukes.

This layer has enabled life in Eolia, as its thickness has prevented the lethal tartarian atmosphere to spread in the Heavenly plane.
