[The Ogre]

That's a true possibility but you'll notice she never goes out. Probably sun allergy or something. She always sends goons or Rosella on quest for objects but never move a finger to achieve her goal herself. Probably she's far too scared of breaking a nail... Or maybe she prefers keeping an eye on Edgar. She does not want to face the same problems Mannaman went through...

Moreover She fears Genesta's power that can be feeled thoughout the land.

And by the way, there's no real evidence her spell would be effective on giants of my size.  Else she would have visited my Hen.

It's more a "I respect your hunting territory" thing between well educated "neighbours". Even if we hate each others.

And I don't like the tiny small road around the castle. I could collapse in the void or make the path fall down under my weight.

Anyway, back on topic i like all your suggestions so far.

Me? Scared by those little flying things? Are you serious? Certainly not! What a joke! I could crush them all simultaneously without effort. The only problem is I can't fly. They're just quicker than me to grab Rosella, that's it. I knew I should have brought a sling!

Well, sure, you could try to crush them.  But I'm pretty sure Lolotte- being a powerful sorceress and all- would sense what was going on and then show up herself to fry you; which she could do just by pointing at you.
