From Skillet's Remnant Wiki
The stitching of the worlds has resulted in two vastly different realms crashing together (literally!). The ethereal, treacherous, medieval realm of the Fae has come tearing into the grey, brick-and-cobble drudgery of the industrial world of the Dran. Each location on Losomn is in one of these distinct realms.

Fae Stronghold
Fae strongholds are almost indistinguishable from Fae Halls. In fact, Fae Halls are simply specific, interior portions of Fae Stongholds. If one judges solely according to appearance, the two seem virtually identical.
