We drizzle the bridge Bifröst - or Bilröst - layer by layer by nýsa niður, and in time, it leads to Valhöll

Bifröst (pronounce ´Biff-roest, accent on the 1st syllable (as always  in Icelandic);
–please do not call our precious bridge “buy frost” – that hurts–)
Bifröst is invisible, made of our purity.  Laid, layer by layer –as if  drizzling stardust– by the most delicate act performed by man in  Miðgarður: nýsa niður (transcend thought and spacetime).
Bifröst is the most precious bridge we can ever make.
-The reindeers?
-Óðinn rides over the sky at yule-tide to chase away wights of cold and darkness. We should be air-born too.
