Have larger land going greatshells existed above a chasm fiend?
Larger than a chasmfiend, the ones out near Reshi can go on land. So yea, it is possible that there are larger ones. They do better in the water, because of how big they are, the high oxygen, low gravity, and symbiotic relationship with the spren allow for mega fauna that is just unrealistically large and just could exist on earth, so yea.
