I literally just did that fight now on hard mode and it almost wiped me too even though I went into the forest by accident (was seeing if I could get Camille a rune before going) so was level 20 off the 1 fight I did there. From what I remember the dragon fight is usually level 15-16 ish. The aoe fire breath you would basically have to cure everyone the turn after it because back to back would kill anyone not named Viktor and his absurd HP pool.
Also did the stone tablet always list Pahn on it immediately after getting it even though he doesn't rejoin for a bit?
