I'm not quite sure how canonical Dungeons and Dragons Online is, but in DDO, Lolth managed to forcibly insert herself into Eberron in the Menace of the Underdark expansion that introduced Forgotten Realms to DDO.the Elven Gods in part or in whole are worshipped in the Forgotten Realm, Greyhawk, Planescape, Spelljammer, Ravenloft, Exandia, Nerath, maybe briefly Dragonlance (I read somewhere that Drow had invaded Dragonlance to spread Lolths worship, but got kicked out), and sort of almost Eberron.
The Spinner of Shadows, a powerful demonic drider, had long been imprisoned in Khyber. . .and Lolth managed to find a way to build a planar connection from her abyssal lair in the Demonweb through to Eberron, and attempted to turn the Spinner of Shadows into an aspect of her, giving her deific access to Eberron.
The PC's prevent this (as adding Lolth as an actual deity in Eberron would be a rather large, world-shaking event for a setting that's in a sort of permanent stasis as it has no official metaplot), but the planar connection is still open, which is the plot device that allows travel between Eberron and the Realms in the game, and that would mean that Lolth could at least keep trying to influence Eberron in the future and find a new way to gain access to that world.
