From a two-year-old s_d thread on Glory of all things

[philippos42]

For a while now I've been thinking that the invisible plane ought to be explained as something Hephaestus made because he just really likes to make stuff for people. Diana of course would never insult him by saying that it's useless.

Hephaestus doesn't get nearly enough play in fiction. I've got a scene in my head where he wrangles a visitor to Olympus into his workshop to show off, and he's got a bunch of stuff laying around that he made for legendary Greek mortals but wasn't able to deliver - a chisel for Pygmalion, a pair of armoured boots for Achilles, that sort of thing.

This amuses me. I love that scene idea.
