Psyched

-Pressing on towards the lakeside resort, psyched of the grand festival, our heroes have arrived at picturesque Hararu Town.

Did I hear of correctly? If not, what would have been used after psyched by the narrator?

The preposition 'of' sounds odd to me. I'd use 'about' or 'by'.

Excellent answer. Thank you.
