My (attempted) unbiased review of realms on Dwilight, from south to north.
Madina: Dead. Easy for a group to achieve an internal coup. Borders roguelands.
Fissoa: Slightly less dead than Madina. Seems to have some active players struggling to attract attention, lately. Between largest realm on island (Luria) and Madina. I think there's some narrative-roleplaying types here.
Luria: Largest realm on island, engaged in long-distance war to colonize a foreign land. Long-time ancient rivalry with D'Hara that ebbs and flows. Recent diaspora of its nobles to new realms. Narrative-roleplaying, politicking, religiosity.
D'Hara: Squeezed between roguelands and east Dwilight. Talkative politicking and narrative-roleplaying types here.
Swordfell: Between Luria and the Former Morek Empire, wealthy, long periods of quiet with spikes of activity, been playing at peace and neutrality between larger spheres of influence since foundation. Politicking and religiosity.
Astrum: Theocracy of SA, quiet, but becoming more invigorated with defending their realm from Luria and Helyg Derwyddon. Religiosity. Close war.
Helyg Derwyddon: Close war on their border, somewhat involved in colonizing Astrum with Luria (some westerners reside in HD). Religiosity (probably least of all the realms I tagged with this).
Morek Empire: The remnants from all the secessions. Been troubled and changing rulers and foreign policy between two 'larger' sides on Dwilight. Few players, but a very active portion of those players, so can be quickly talkative place. Easy for a group to achieve internal coup. Religiosity.
Antiqualia: Close war on border with Arnor, but lack of ability to really do much atm (limited recruits and other resources). Enough players might change that akin to DSS on EC.
Arnor: Trying to bring AQ to peace via war. Seeking to hold itself independent without foreign influence in the north. Expects much war ahead.
Edit: Realize I forgot to mention above that Astrum and Arnor border roguelands as well.
