Here's a selection of letters from the ancient Terrahyptian era before Yluxa. Some letters use Swedish vowels, which I personally think is useful because they more accurately represent the sound. And unlike IPA, the letters "Ä" and "Å" is available on more systems than "ɛ" and "ɔ".
Though I understand why you would use Swedish vowels instead of the IPA, the linguist in me is disgruntled.
Fasmei, Raidyutan, Tsära, Snyfs, Säisyris.
Can't they just smear their snyfs onto the paper?
Thilians are not really Terrahyptians, they're just hitching along for the ride to put it bluntly.
