Le Pétit Prince
Although not universally terrible - there are some cat-sized ones that could be tamed as effectively as any other type of bird.
Tiatus - Dreadnought
Phase: Rebellious Client State [Ekkadey], Rising Monarchy
Military Power: Strong, defensive, organized
Cultural Power: Derivative, resistant to influence, non-assimilative
Economic Power: Medium tax base, high manpower, some basic resources, luxury-poor
Yes, based on how related your foundational myths are, I saw Tiata as being under Ekkadey hegemony at first before breaking free. Although you and Thomas are welcome to work out an alternate narrative.
