So, I was wondering a little bit about whether or not Au Ra hear through their horns, or if there's another "ear type thing" that they hear from. From the Wiki, it says that they have enhanced hearing thanks to the "cranial projections" on their head, the horns.

Wondering if anyone has some lorebook entries that can clear this up. Also, are the horns hard, or are the soft and bendable, like an ear would be?

I can't imagine sleeping is easy for Au Ra, with those horns projecting out.
