looking for good wyvern games

Hey, I'm pretty much obsessed with dragons, wyverns specifically. Ones like the ones from GOT or HOTD. I am searching for free, best with private servers games, that will either allow me to be a wyvern and fly with it, or to ride one. I am not really good at pvp or battling, so I'd appreciate ones that are either just one with easy lore, or a simple rrp. I would really love if there's a game based on Westeros, though. Or ones with four-legged dragons, if there are no wyvern ones.

I have played dragontwin, probably all the ones on roblox (I'll take suggestions on roblox too. I've played the hotd official game, clash of dragons and realm of beasts), and i've tried multiple mods on minecraft, But i am not against advices on those too.

Thanks for anyone that comments, and sorry for any mistakes in my text, English is not my first language!
