Echo location only works if there is a surface that the sound can reflect off. If you are talking about walking off a cliff, echo location is useless, since it will not reflect off air. It bears mentioning that absence of evidence is evidence of absence. If there's no reflection off the ground, there's probably no ground either; you should be able to notice the difference.

I watched once a documentary where a blind person was able to use echolocation to walk around and do stuff, by clicking his tongue and listening to the return sound; and there exists an archer who is an olympic recordsman despite being legally blind (granted, he does have some eyesight left). If this is physically possible for an individual (no evolution, no natural selection) in real life (no fantasy), I guess it should be believable for a fantasy species to develop similar abilities over a few thousand years and a few hundred generations under harsh evolutive pressure.

Also, Falmer stop seeing you if invisible, invisibility and muffle aren't one package. [...] while gameplay != lore, this is not very valid since game play must be based on lore not just for immersion, but also to actually tie the lore into the game Personally, I'd probably call that a limitation of the medium and let it slip.
