The bloated corpse of a decaying gigantic creature is necromatically enhanced and fused with an undercarriage for use as a grisly and terrifying airship. The methane gas from tissue decay keeps it buoyant in atmosphere, but it can be even more flammable than hydrogen if it escapes...
There is a race of beings that have endless lifespans. Because of their eternal existence, the only forms of time which they understand are being and non-being. They do not understand words or ideas such as past, future, present, yesterday, today, tommorow, then, now, when, until, ect. They do understand yes, no, live, die, on, off, there, not there, existent, non-existent, ect.
