FTP, name this giant ash, the world tree in Norse mythology.
Askr and Embla were born from it, four deer run across it, representing the winds, and the Roaring Kettle, which serves as the source of rivers, lies beneath it.  Also known as Laerad, Heidrun and Eikthyrmir eat from it, and Lif and Leifthrasir will use it as shelter.  Urdarbrunnr is used to sustain it while it holds together three levels that contain the Nine Worlds, (*) and the Aesir hold court here.  Nidhogg gnaws at the base of it, and it will eventually be destroyed by Surt.  The source of the mead served in Valhalla, Odin hung upside down for nine nights from it to receive runes.  The golden bird Vidofnir is perched on a hawk at its top, and Ratatösk runs up and down it delivering messages.  FTP, name this giant ash, the world tree in Norse mythology.
