Eltux is the Meridia of the Colour Blue. So he's why the sky and sea are that colour! Does that mean he's to blame for your bruises too...?
The Meridian Effect
Today is the ideal day for diving headfirst into your dear one's ocean-coloured eyes. Why don't you give a rendition of the song Behind Blue Piwis or offer her a necklace made of blue-tinted metal? There's no need to feel blue... Well, there is but... you know!
