The Halfway Inn is described in The Sword Coast Adventurer's Guide as being commonly referred to as “Evereska’s Trading Post” straddling the forest and mountains of the elves of Evereska and the edge of the great desert of Anauroch. It serves as a place where traveling merchants often exchange goods. Specially crafted items brought to be traded by elves can also be found.
The Forgotten Realms wiki describes the Halfway Inn in past tense as if it no longer exists.
This leaves two questions. Does the Halfway Inn still exist in contemporary Adventurers League play? Has any published adventure ever detailed the Inn?
