Could there be a relatively peaceful solution to the shard problem?

Would that mean Lahabrea is remembered as Llymlaen? Their names both start with "L", after all, which is certainly a coincidence. Lahabrea has very little to do with oceans and navigation, but that could also be explained in-universe by a ten-thousand year gap.

Could be. Gods can and have had radical changes in how they were worshipped and portrayed. Look at Dionysus for example.
