I was looking through some old screenshots yesterday and found one of me, as a hatchling, in a very deep hole.
It's southeast of Jeanne, at 22883.83 / 16143.71. Jumping off that cliff to continue westward is a risky move as there's a few places there where bipeds and hatchlings can fall and not get out. Go for a dive, if you feel bored!
Ahem.
So, where are your favorite terrain traps? I'm talking about the ones that leave you swearing as you slam the recall button.
