Ok, once you're outside of the Mysidian Tower, there's something you should know: The following areas have been destroyed now by Emperor: Altair, Gatera, Paloom and Poft, are all destroyed now. Shit, I know. This is only the start of it, too. Mysidia, Fynn, Salamand and Bafsk are all that remains in terms of towns. Also, new Enemies have popped up all over the world now, mainly the ones you've been fighting ever since taking over Castle Fynn up to the present. None are that hard, but the Enemies literally outside of Fynn are a GREAT source of Gil, as you'll get so many expensive drops, you'll literally make a fortune in 20 minutes, I guarantee it. Anyway, I suggest you fight around Fynn until you get the Haste Scroll, which IS sort of worth it, but don't go nuts if you can get it.
Other than that, when you're ready, head over to Castle Fynn and go see Princess Hilda, as you see Leila is alright! Whew, at least she survived and didn't die like the rest. Anyway, Princess Hilda tells you Emperor has made a Cyclone and how it's destroyed the 4 towns I mentioned and they're next. Memorise Cyclone and ask her about it if you wish, then ask her about the "Wind Drake". She tells you about people calling a Wind Drake using the Pendant on the castle mirror here. So, to get to this mirror, head back to the first floor and once here, head southwest and go up the stairs here and in the next area, go up the stairs here as well. On this floor, head north and enter the door here and in this room, go north and examine the mirror and use the Pendant, as the Dragon Egg appears and a Wind Drake is born and you obtain it.
After Gareth and the Wind Drake meet, go ahead and leave Castle Fynn and at this time, sell anything you don't need, restock on what you do need and heal up. Also, go and talk to Pavel NOW, because if you don't, you'll never get these Items again. Tell him "Cyclone and he'll let you have his secret Items near his bed. So, examine the wall near his bed to find a room with 8 Treasure Chests that hold a Ninja Suit, Thief's Gloves, Elixir, Silver Plate, Ruby Plate, Gold Plate, Gold Hairpin and a Blood Sword. Again, do NOT sell the Blood Sword, as you'll want both for the final Battle. So, sell off the rest of this stuff if you don't need it and keep what you want and when you're ready, leave Fynn and head north to find the Cyclone and go near it to have the Wind Drake fly you into the large castle that's inside…
