The Tomb of the Unknown King is an interesting dungeon which you will travel in a pseudo-first person perspective. You can bring up a map by pressing Select (which will show your location as a red X if you bought the location displayer in Deling City). You can automatically exit the Tomb at any time by pressing Triangle on the map screen, but it will cost you 1 SeeD Rank.
Your required mission here is very simple. Just two screens into the Tomb, you'll find a sword on the ground. Examine it to find the student ID you're looking for. At this point, you can return and continue the plot. However, if you continue to explore, you can earn the Brothers GF.
To earn the GF, you'll have to visit the three outer rooms of the Tomb in the order east, north, and west. The simplest way to do this is just to go right at each intersetion, which will loop you around the outside of the Tomb.
In the eastern room you'll fight Sacred. You can use his Protect Spell to reduce the damage he deals. He will regenerate HP unless you cast Float on him.
Defeating Sacred will open the other two outer rooms. Continue around to the north room for a Float Draw point, and drop the dam you find there. From there continue to the western room and use the gears to lower the central drawbridge. If you have Move-Find on, you'll find a Cura Draw point and a Save Point here as well.
With all that done, head for the central room. The drawbridge is directly north of the entrance, crossing the south side of the moat.
In the central room, you'll fight Sacred again, but this time his brother Minotaur joins the fight. Once again, Float cancels their regeneration, but it also serves as a defense against their Mad Cow Special (an Earth attack) when used on your own party. Minotaur is more powerful but has less HP, so target him first.
