Irelia isn't an elder, Karma is. you should change queen into karma instead and the other bishop into Janna (she thought karma how to use the art of mantra in conjuction with her fans).

you can place shen as king since he is the leader of the kinkou ninjas (akali, kennen)

As for Freljord, here is a list of champions that has any sort of ties with freljord:

Ashe - Queen of Freljord

Trynadamere - King of Freljord; High Chieftain of the Barbarian Tribes

Nunu (and Willump) - League Emissary of Freljord

Gragas - Owner of the Avarosa Iceflow Glaciers

Olaf - Regular costumer of Gragas (hinted by his Brolaf skin)

Jax - Gargas drinking buddy

Sejuani (and Bristle [Kevin Tuggles]) - Ashe's cousin; Winter Claw Tribe's Princess; Currently at war with Ashe (she can still be part of your chess cause she's in direct conflict with Ashe only and not with Freljord itself)

Volibear - High Cheiftain of the Ursine Tribes

Anivia - Residence; Friend to Ashe, Nunu and Willump

Cassiopeia - Cursed Frljordian Diplomat (ya, forget about putting her in there)

Sivir - Residence; Built a mansion in each city-state (I don't know about her though)
