The Forgotten Realms wiki entry on Laerakond says:
Laerakond [...] was a large, horseshoe-shaped landmass, west of the Trackless Sea and north of the Great Sea. (...) Laerakond was located near Evermeet, in the Great Sea the to the south of the elven island.
The entry on the Trackless Sea says:
The Trackless Sea was the name of the ocean due west of the continent of Faerûn. [...] The Trackless Sea ran from the Sea of Swords in the west [east?] to Maztica, [...] and Anchorome in the east [west?].
The Great Sea entry says:
The Great Sea was [...] lying between the continents of Faerûn and Zakhara, and, after the Spellplague of 1385 DR, between those two continents and the new continent of Laerakond.
And the entry on Anchorome says:
Anchorome [...] is the far western continent of Toril. It lies roughly 3,000 miles (4,800 km) west across the Trackless Sea of the Sword Coast, or about 1,000 miles (1,600 km) west of Evermeet. Anchorome is directly north of Maztica.
Returned Abeir becomes the identical continent of Laerakond, well southwest of Evermeet
From all that chaos, I can imagine the Great Sea stretching between the shores of Faerun, Zakhara, and Maztica, with Laerakond being somewhere near the Chult - Maztica line, quite close to Maztica (less that 500 miles) according to Ed's description and the size of Laerakond, which different maps estimate at around 1000 miles.
Is my deduction correct? Am I missing something?
