When you travel west from the Gnoll Stronghold, the journey to Ormyrr's Peak is automatic and instantaneous instead of selecting it on the world map, while vice versa it takes the proper four hours as listed.

Yes, it's for the sake of compatibility, as I do not want to change search regions unless it's a total must. It only affects the game one time and it's a fair price for keeping things safe. 

Also, is there any way to obtain "gold teeth" without having to rob a tomb (for RP reasons)? At first I was sure he simply meant gold pieces, but alas that didn't work so I consulted the walkthrough and found out that I'd have to do that...

No. If you're not comfortable with this, then perhaps just skip the quest. That's also part of the role-playing. 

I think "Ormyrr Peak" would be a better name (the generic singular implies the plural – cf. "Xvart Village"); or, if you really want to emphasise the plural, "Peak of the Ormyrrs". Amazing detail on those Ormyrr corpses blended into the area background, by the way – did you create those yourself?

I like the name as it is, even if it may sound imperfect. 
As for the Ormyrr corpses, they are based on Pool of Radiance: Ruins of Myth Drannor.
