Notes

Make a language based on the english alphabet but simplier to write than english and takes less time. Nahantal would speak in this language and would be the person that he others are most familiar with. Nahantal would be less modern than everyone else, as he sprinkles some words that modern day people use (text messages and irl) while many just use text.
For example
"How are you today?"
"Hw r u dy"

Numbers would be adopted into the alphabet and used interchangably with words.
"I'm doing well."
"Gr8"

With simple sentences, there would be no period at the end. However, when doing multiple sentences, people would use periods, though not at the last sentence.
"I found you floating in the tube. Primitive technology. I thought I would need to call authorities to help me, but that would be awkward."
"Found u in tube. Last gen tech. Thought need bots but thats awk"

Does away with most forms of punctuation (most notably commas and apostrophes) and tenses. Only used when absolutely necessary.
"My name's Nahantal Adrem, but just call me Nahantal, or Nahn if that's too long. This here's Odyssey, my botpal, but just call him Ody."
"Full names Nahantal Adrem but call Nahn if Nahantal too long. Thats Odyssey uh botpal but call Ody"

Often shortens long words.
"Great, the authorities are catching up to us again. I hate this..."
"Gr8, bots catchn up to us. H8 this"

For Nahantal, never translate him saying
"Shut down Ody!" or when Ody is saying "Shutting down..." or any other commands of Nahantal to the botpal.
