Strago and Lore

Tower of Fanatics

Strago is walking around the Base of the Tower of Fanatics, apparently hypnotized. You can't do anything about this until you've recruited Relm. if she's in the party, she'll wake Strago up and he'll immediately join the party. (A woman in the West Wing of Figaro Castle mentions that calling out a loved one's name will wake them up from the Cult of Kefka.) You can try climbing the Tower of Fanatics, but it is a difficult and specialized climb where only Magic is allowed. The boss at the top requires Phoenix's Life 3 (or other shenanigans) to survive against as well. Don't attempt this dungeon until you're prepared.

Lores

Now that Strago has joined, you can travel the world to learn various Lores. Relm can help with her Sketch Command. This list covers Lores that you can learn in easily accessible random Encounters. There are other methods, such as fighting Monsters on the Veldt or saving monster-in-a-box chests until Strago is available, that are not covered here. Checking the page for any given Lore will indicate other possible ways to learn them. Any Lores that can be learned in future dungeons will be pointed out at that time.
