His name is Firekraag, or something similar. Edit: My bad, this was in Baldur's Gate 2. If we're going to "trip" over the difference between wyvern and dragon, the definition of wyvern says:
wyvern [ˈwīvərn] NOUN heraldry a winged two-legged dragon with a barbed tail.
The dictionary definition is irrelevant. In any other context I would agree with you about wyverns being dragons, but not today. You know full well you weren't thinking of the wyverns when you wrote that there was a "red dragon" in BG1 and that was what I responded to when I said "no dragons". You even said you were thinking about Firkraag from BG2 yourself. Wyverns are not interchangeable to dragons in context of dnd -- where saying "dragon" assumes you are talking about "true dragons" and not any other kind of synonym-for-dragon-in-the-dictionary such as drake, lindworm, serpent or python -- and much more level appropriate to BG1s level range than a red dragon would be.
