>> They don't seem like words that people would jump to when they want to name something so important and omnipresent in one's life.
I didn't think of that Wildblow, however I disagree with you on the names not sounding important. For our world, maybe. As for this planet? Well it's more mythical or fantasy-like with hints sci-fi elements and people can use other sources of communication besides the "internet"

I'm feeling Irdescention or Iradea/Irada/Iradia for short
