Utterdark and Second Sun

Actually, a greenhouse works by letting light in, but not out. So I think the the great Fluff wont be appeased by that explanation

The obvious explanation is that Utterdark blocks visible light, so you can't see anything. The UV and IR radiation from the Second Sun will still get through, however, so you'll still get heat and a nasty sunburn.

Ok, so maybe not a greenhouse. But visible light can be blocked while heat still comes through. Especially using Medieval physics. If second sun increases heat scale, and utterdark reduces heat scale (does it?) it might come out with an appropriate result.

Well... Actually the spectrum of light from the sun is peaked around the visible area (otherwise evolution would have had some explaining to do ).

But of course, there is no reason for the world of dominions to have to be all scientific - it is fantasy after all. But still, details are nice - and having the combination of utterdark/second sun do something special would be fun I think.

Sure, the NORMAL sun does that, but Second Sun is inherently unnatural. More importantly, since it doesn't actually cause units to explode into flames or go blind, like the real sun does, it's probably a big IR lamp.

The spell text actually says "The caster creates a huge ball of fire in the sky. This second sun will always shine, day and night, ..."

But of course, a huge ball of fire COULD emit mainly IR light...

OK, this is getting silly

Actually there would be nothing inconsistent about a patch of darkness blocking visible light and heating things. It is happening even now for real, ever heard of pollution?-p Some studies say the world has become dimmer for it in recent decades, and... ...I think it might be best not to discuss global climate change on public forum in internet... I've seen where it can take you.

Dark things absorb visible light and heat up, releasing IR radiation. All very real-life physics, not many inconsistensies.

Except, of course, that magically created second sun and forced eternal darkness.
