Typically, mountain top look-outs look<em>out</em>rather than down.<br/><br/>It's a side effect of the fact that you can't really look straight down without coming right to the edge.  On either a natural surface or a crumbling ruin, smart people don't trust their weight to the weakest part of the rock.<br/><br/>Of course, we're talking about Goblins here.<br/><br/>I'm just saying that there's a reason someone like 007 infiltrates mountain villas by climbing up the sheer stone face rather than bluffing through the front door with a costume and a plausible lie.<br/><br/>(That reason is that it looks cooler, and Narrative Causality is a thing).
