Vault of the Drow: EXPLAINED! Drow are future Dutch.

Any sufficiently advanced technology is indistinguishable from magic

Arthur C. Clarke, "Profiles of The Future", 1961 (Clarke's third law)

Nobody can whine any more about the ecology of the Drow or the underdark. Indeed, I have found a few clear conclusions based on the link I will reveal below.
1) The elves are the descendants of Dutchmen.
2) So, therefore, are the Drow.
3) Greyhawk is a future world.
4) The Drow make use of diode technology.

Here, my good friends, all is explained. Does the italicized text sound familiar?

Meeuws and three other Dutch bioengineers have taken the concept of a greenhouse a step further, growing vegetables, herbs and house plants in enclosed and regulated environments where even natural light is excluded.

In their research station, strawberries, yellow peppers, basil and banana plants take on an eerie pink glow under red and blue bulbs of Light-Emitting Diodes, or LEDs. Water trickles into the pans when needed and all excess is recycled, and the temperature is kept constant. Lights go on and off, simulating day and night, but according to the rhythm of the plant — which may be better at shorter cycles than 24 hours — rather than the rotation of the Earth.

Oh yes, we all know where there are eerie pink glowing plants and tricking water. Nobody's fooling us. We know exactly where this trend leads. It leads to spider worship.

Here is the full link.
