Yggdrasil

I know a mighty ashThat spreads all over earthThe greatest of all treesStanding over the skyThee roots it hasOver three wellsYggdrasil is its nameAnd many creatures dwell withinThe first I know is with the godsIn heavens up highThe second I know reaches towhere emptiness once wasThe third is far belowIn the darkened realmOne creature is a burden hereGnawing at the rootsEagle of great knowledgeDwelling in the branchesHawk between its eyesIn Yggdrasil's mighty heightsRatatosk, a beast of slanderSpreading vicious liesAnd four slags running in the treeDevouring the leavesI know an ash standingYggdrasil heighta lofty tree, lavedwith limpid waterThence come the dewsinto the dales that fallever stands it greenover Urd's fountainThe mighty ash, Yggdrasil....
