The Undying Lands

[Lalwendë]

Very big I hope. Has anyone else ever thought about the simple maths - a load of immortals and all their immortal descendants would make for one enormous population. Maybe Valinor was like something from a dystopian Sc-fi novel with towering skyscrapers where each person is allotted just seven feet by three of living space? Or maybe they had discovered how to shrink themselves as seen in Kurt Vonnegut's Slapstick?

A short description is given in the Sil:

It seems that the place was quite large .

I would also speculate that Aman was quite fitting - besides Valinor, there was also Araman and Avathar; plus, Tol Eressea too was removed after the Akallabeth, "beyond the reach of Men". This could mean an alternate reality, whatever that is - perhaps something similar to the shadow world of the ringwraith; or it could simply mean a another planet in Ea.
