A steed generally means a fast horse used for riding or battle. In slang terms it can refer to a person's unique style.
The "World Tree" in Norse mythology was called Ygdrasil (Otherwise spelled Yggdrasill). It was a giant Ash, whose branches and roots held all the nine worlds together: Asgard (Home of the gods), Alfheim, Vanaheim (Home of the Vanas), Midgard (Middle Earth), Jotunheim (Home of the Giants), Svartalfheim, Niflheim (Home of nothing / the dead), Muspellsheim (Home of Fire) and Helheim (The Underworld) The tree was tended to by the Norns; goddesses of the past, and constantly gnawed at from its roots by the wyrm Niohoggr (Nidhogg) in Niflheim. It was fortold that one of the heralds of the final battle would be the fall of the tree; when Niohoggr finally chewed his way through its roots. This prophecy was eventually fulfilled. The name Yggdrasill is thought to originate from Odins own; "Ygg" meaning Terrible one (one of Odins many names) and "Drasil" meaning Steed... Ygdrasil being Odins tree. The tree was also variously called Mimameidr; meaning "Mimir's tree", and Laerath; in the Edda of Balder's dream.
War steed or War horse may be equivalents of 'val-raven'. The word is used in science fiction and fantasy literature. It draws upon Norse mythology.
