I'm currently trying to remember the statues in Lindblum, as well as the armour set in the Conference Room place. Been too long since I played it. My logic being that all these things were made in Lindblum, and I think they refer to Cids 7, 8 and 9.

The link to Tetra Master is that Cid 9 is the official Tetra Master bloke.

I'm fairly certain that the Lindblum statues and the Cid equipment are both incorrect, but for the sake of progress that's my guess.
