Thanks for your question! The only form of punctuation in the dragon language is equivalent to a dash or hyphen, which could be used to indicate dialogue.

Direct speech would require the "dialogue tag" ("he said", "she said", etc.) to come first so the reader knows what follows is dialogue. Here's an example from the game:

Noble Nord, remember these words of the
Hoar Father - even the best steel
may bend and break but the flesh of
true men is unyielding.

Unfortunately this punctuation is not available in the current font, but resembles a diamond shape.

For indirect speech, the prepositions do 'of' is used (or no preposition at all). Here's another in-game example:

And the Scrolls have foretold of black wings in the cold
that when brothers wage war come unfurled.

When it comes to human speech, you would use fun 'to tell'; Bormahi fun do lot kein lingrah vod "My father told of a great war long ago."

Quotation marks are not used or known. In word wall-esque writing, a line break can indicate a quote. Otherwise indirect speech is analogous to that of West Germanic languages:

Bormah tinvaak

zu'u los kras

"father spoke: 'I am sick'",

bormah fun/tinvaak tol (rok) los kras

"father told/spoke that (he) is sick"
