If it were to be written phonetically (based on how it sounds), it might be written like [he9den luwelin].

The main pont of difference is that the dragon language doesn't use "Y" as a vowel, so "ay" can use the letter [ey] (sounds like the "ey" in "hey") and [i] (often pronounced like "ee" but sometimes the short "i" as in "in") can be used instead "y" at the end.
