(P)lato's (S)pawn cold (I)vyed eyes

The Greek letter PSI reminds me of Poseidon's trident.

It's the symbol for psychology: another connection to archetypes.

"Ivyed" an unusual adjective for eyes, yes?

A reference to Ivy league, perhaps?

in any case, I do believe the selection of an "I-word" (eye) to be intentional for the above reason.
