Does anyone know these things?
Have you noticed anyone playing a drum?
[spoiler]A DRUm? I'D look for somewhere low-tech.[/spoiler]
[spoiler]If she's still playing it, come back later.[/spoiler]
I got it, thanks. Now where to use it?
And the horn. I know it is in the picture, but how to get it?
Have you been to the City of the Winged Ones yet? Try talking to the Muses and Lord Azure and Lady Ariel for some hints on where to use the drum.
As for the horn, perhaps you can pull a switcheroo.
