Technically, yes (since any zone that is duplicated for a raid instance will have the same basic objects/structures/locations).
Is: an object, a structure or a location within a zone, located on Norrath, in a zone related to one of the last 3 expansions, something that is only in one zone, in Antonica, in some kind of structure, in a raid instance (technically, but that might be misleading). Is not: a zone, an item, Breath of Harmony, an NPC, the doodoo on the ground in Freeport, located in Freeport, some other kind of fecal matter, to do with House of Thule zones, the Morituus Monument, located at 101 Market Heights, Spruce Island, on the Bert server, the large shard zone in shards landing, a living orgasm (or organism), in the Feerrott, eeeeevil, an object that can be interacted with, in Chapterhouse.
Oooh, unintentionally tricksy! It is not an eyeball, and no eyeball makes up part of the actual answer, but it does contain an eyeball.
