Bag End was a spacious Hobbit-hole (or smial, as they were called in that time) reputedly built in the side of the Hill near the Water. A smial was composed of a tunnel or tunnels and rooms dug into the ground. Hills and banks were the most suitable locations for smials.
The tunnels of a smial were generally tube-shaped with round doors and round windows. The simplest smials had dirt walls and floors, while the better smials had panelled walls and tiled floors. Some smials were very small, while others had several branches and rooms. Bag End was an example of a large, single-family smial that had many rooms on either side of one main tunnel (which had two main entrances).
After the War of the Ring (at the end of the Third Age) hobbits faded into legend. All that we know of them today has been recorded in stories and songs passed down from that fabled time. Upon occasion men will stumble across works left behind by hobbit hands, dismissing them as natural occurences in the lay of the land. This is one such place... could the two portals that give access to this tiny realm once have been the entrances to Bag End? Does the site's proximity to the Water (Cook Inlet's just over two miles distant, and a fair dozen small lakes lie even closer) and its terraformed hill-shape give any clues to its use in the Third Age? Come see for yourself what treasures may lie behind the two portals...
Do not disturb the location or add to its camouflage.
What exists now shields it from the casual passing eyes of Man...
Enter ONLY via one of the Stone Portals!
Roads go ever ever on,
Over rock and under tree,
By caves where never sun has shone,
By streams that never find the sea;
Over snow by winter sown,
And through the merry flowers of June,
Over grass and over stone,
And under mountains in the moon.
Roads go ever ever on
Under cloud and under star,
Yet feet that wandering have gone
Turn at last to home afar.
Eyes that fire and sword have seen
And horror in the halls of stone
Look at last on meadows green
And trees and hills they long have known.
