okay so here's the deal

the leviathan in this base was a Sea Dragon Leviathan

The only time I've seen a Sea Dragon Leviathan in-game without spawning it myself was in the Inactive Lava Zone outside the spires of which I think is the Lava Castle (Experimental)

In front of the Aurora is a very big hole, this leads down to the inactive lava zone, and straight to the Sea Dragon Leviathan

It's my best guess that the Sea Dragon I saw is supposed to be the escaped Sea Dragon from the facility, that fled into the Inactive Lava Zone from the Lost River

This is just an assumption, but I believe it could be accurate.
