Well maybe im wrong, i dont know where she is. Cant wait for the next chapter release, all this pieces of information the author is releasing is so vexing that i want more of it.
Yep he did. Shirahoshi is the ancient weapon 'Poseidon'. She can control Sea-Kings with her voice. The second weapon was the ancient warship that could be used as a WMD and not much is known about Ur anus. https://onepiece.fandom.com/wiki/Ancient_Weapons
