It's clear at this point that you meant South Yorkshire, Greece, and the password must be 'hippos'.
#1: 'To carry Undomiel' sounds like we're looking for Arwen's horse (which is what put my in the horsey mindset to start with), but I don't think she has a named horse. (I said
doesn't; put Asfaloth back!)
On the other hand, what she does have is a grey PALFREY to take her to Minas Tirith, which is pal + Freya. So I'd say that'll do nicely.
