The gas most likely is one of the noble gases.
Noble gases are commonly used in lighting because of their lack of chemical reactivity. Yet even better known is helium's use in balloons because it is lighter (less dense) that the surrounding air it causes the balloon to rise. Helium is sometimes used to improve the ease of breathing of asthma sufferers. Xenon is used as an anesthetic because it can be moved quickly from the body resulting in faster recovery. Another noble gas, argon, is considered the best option for use as a dry-suit inflation gas for scuba diving. Noble gases are being used more and more like in blimps or crisp packets.
'Royal gas' is not a term used in chemistry. Perhaps you mean "noble gas", if so yes "inert gas" and "noble gas" often mean the same thing. However, oxides and fluorides of some of the "noble gasses " do exist, it might be best to think of them as "noble" rather than "inert". Xe, forms oxides.

Please provide the quotation you would like an explanation of.
The noble gases are a group of chemical elements with similar properties. They are odorless, colorless, and have low chemical radioactivity. The 6 naturally occurring noble gases are:Helium (He)Neon (Ne)Argon (Ar)Krypton (Kr)Xenon (Xe)Radon (Rn)
Solids, then liquids, and lastly gasses.
