Spoilers for the Omega storyline:
At the end, Hraesvelgr is able to travel into the Rift to rescue Cid and the WoL after Omega's defeat. However, traveling into the Rift doesn't necessarily mean he could go to another Shard; it's like going for a swim at the beach versus swimming across an ocean. It's also implied that only an excessively powerful dragon like one of the First Brood could do it.
