Holy crap on a cracker that's a lot of offerings, Rhi. xD
How could I ever pick between them?! *_*
They're all so awesome! Niaaki, Valor, and Liadan are the most tempting. Liadan because she seems adorable and sweet, Valor and Niaaki because I think both could provide some interesting headaches for Dimitri! xD
Do you have any preferences between those three? Can you imagine some fun thing you want to do with Dimitri in regards to any of them? For Liadan I could see her using her cousin's newfound station to secure a better marriage. Niaaki, uhm...could try to take sanctuary with his cousin? After...something. I don't really know. Valor is a party boy and could just decide to hang out with his cousin because High Lord, so could try to milk some freeloading at Rillaria? lol
And Deli, it is possible that they are 2nd or 3rd cousins - might even have contributed to helping Dimitri become High Lord. Everything is about connections, after all.
