Beavisland
And a few miscellaneous notes.
I got the one item in Karnak that you can't get until after the castle goes kablooey.
Also I trained up a Beastmaster to get Control and learned a few more Blue Magic spells.
Not that the Chimeras need any prompting to cast it. They can also easily wipe your party at this stage so it's a bit risky to engage them. Fortunately they're easy to kill by just using a fire/ice/lightning rod from Karnak as an item in battle; it breaks but creates a -ga level spell effect, which will kill them in one hit.
