Re: angie!
Gwyn will go to Athena for advice and stuff? Hermes misses you, sis - you guys will interact somehow~ Uncle Hades is probably far too beneath you, though huhu
Famine can have fun with Hermes/Hades cos these two have gotten around quite a bit. 8) & because Hermes/Hades have CR with Raven too, so that's a decent starting point.
Pollux lived in Glastheim for a bit, so Gwynevere, maybe? They're kiiiiiind of in-laws by now. In-laws thing should pretty much apply for Castor, too.
