"Assault?" Gesen asked in confusion, "From where? Isn't there only this one path here?"
"No," Edwin shook his head, "You can't see it, but I flew over the boardwalk and abyss on a griffin and saw a nondescript stone platform above the pass. Deep within that platform is a dark hole, seemingly a ventilation opening carved out, probably only as tall as a dwarf. It should be a maintenance passage left by ancient dwarf engineers, and I guess it leads directly to the back of Stone Gate Fortress."
In these pitch-black cliffs and abyss, the dwarves below truly cannot see the small, dark cave entrance hidden within the platform, more than a meter wide and high, dozens of meters above.
