We know that Vabbi was beloved of Lyss and llya. She especially blessed the land with her Seborhin Tree. No wonder they love luxury and theatre.
What lands/peoples are favored by the other God/desses?
I suspect that The Shiverpeaks are Grenth's stomping grounds. He's the lord of Ice and has a large temple there still in GW1 and 2. Does he favor The Norn?
Istan would seem the natural choice of Kormir.
Maguma for Melandru? Is she also the patron of The Asura?
What happened to the Stone Summit Dwarves after the invocation of The Great Dwarf?
