Sheikah we can assume have died out due to no evidence of them existing at the time of the game. The mask of truth and the gossip stones aside (i suspect they were tools made in the Ikana/Garo war, for means of info gathering), the Picori don't make much a threat due to them being mostly peaceful creatures, as is it would take many of them to fell a single person let alone a goron/Zora/Garo/Ikanian. The Deku would be the most viable in a battle with the Picori but even then only the smallest would work.
Yeah, just pondering on how they could be there as the OP said and because of what G-king said. I'd assume the Shiekah died already, just saying they were likely there at some point before due to the Gossip Stones and Mask.
Hyrulean Gorons have never been unable to breath under water regardless of what age they are from. I would also like to see evidence that Terminian Gorons die from water. Link can't change masks under water as far as I am aware. If he was a goron and fell into a well he would never be able to get out. Even if some areas have a slope that a Goron could leave the water, there are areas that don't have that. Therefore they had to make Goron link die when he falls in water.
Terminian Gorons do not need to breath. We know this because they can survive being frozen in a giant snowball without oxygen. There is no reason for water to kill a Goron.
It says on Darmani's grave... and if they were frozen, wouldn't that be like being frozen in sleep, you might as well say Captain America doesn't need to breathe...
