after a time therefore when the travellers had rested he des- patched the younger of the two guardians of turin back unto mavwin , for such was that man 's desire to die in the service of the wife of urin , yet was an escort of elves sent with him , and such comfort and magics for the journey as could be devised , and moreover these words did he bear from tinwelint to mavwin : `` behold 0 lady mavwin wife of urin the steadfast , not for love nor for fear of melko but of the wisdom of my heart and the fate of the valar did i not go with my folk to the battle of unnumbered tears , who now am become a safety and a refuge for all who fearing evil may find the secret ways that lead to the protection of my halls .
