From what I have studied and from my own experience, I have tended to lean towards Eshu/Elegua myself.

This comes from the following description:
Eleggua / Elegua: Messenger, Opener of the Way, Trickster
Aunbis, or what I refer as Anup Ophis, literally means "Opener of the Way".
I know.. but i got stuck on the Esu being the Orisha of the crossroads that place between the physical and spirit world...
Whereas Anubis (if i'm correct) deals strictly with the Dead, the underworld... i think he escorts the spirit of the dead to be judged..and embalms them or something
Well Oya is the same.... other than the Thunder thing she is the only Orisha who deals with the dead the others are apparently afraid and she escorts and guards the spirit of the dead during their journey to Orun...
so I donno know..leaning towards her...
still working on it though ...just wanted to get your input..cheers
oh and her colors are red and black
