I like the Raven Queen since well for me she just reminds me of a combination of Neil Gaiman's Death and the Celtic the Morrigan. Winter is also my second favourite season, plus fate weaving is neat.
I also like Sehanine since I enjoy characters that use trickery and illusions. Plus I love the night time (the moon) and autumn is my favourite season.
I'm playing an Eladrin cleric of Correlan multiclassing into wizard. We also have a minotaur fighter multiclassing into a cleric of Bahamut (repenting for past evil deeds), and a paladin of The Raven Queen in our group.
I limited myself to two choices - Kord and Bahamut. I've played both a cleric of Kord and a paladin of Bahamut. Others I like the write ups of are the Raven Queen and Moradin.
