Chasm of Ilmen
The Chasm of Ilmen (Qenya: Ilmen-assa) is the gap between the edge of the World and Vaiya. It is filled with the air of Ilmen.
Where the interior seas fell down the Chasm of Ilmen, their waterfalls made bridges of ice which close the chasm. The ice extended to all Vaiya and even the Ilurambar.
Tilion who guides the Moon plunges in the chasm between the western shores of the earth and Vaiya, the Outer Sea.
Other versions of the legendarium
Christopher Tolkien notes that in the Ambarkanta, as well as an earlier unfinished version of the Silmarillion (c. 1937), there is a chasm between the Earth and the Outer Sea (=Vaiya), into which Tilion guides the Moon. However for the published Silmarillion, he preferred a later passage (c. 1951) where Tilion plunges into an unnamed chasm which is beyond the Outer Sea (=Ekkaia). In a later note, Christopher accepts that although his father wrote that, it is not what he intended, and the Chasm lies before the Outer Sea, rather than beyond it.
