Pros:
-Has exceptional RCs (probably more exceptional RCs than any other realm in the game and won't be beaten unless other realms take Astrum's cities)
-Has gold to support
-Astrum's geography (3 cities connected by a single sea zone)
-Surrounded by allies (One being Westgard which is the most populated realm on the continent)
-Rich history (One of the three pillar realms of Sanguis Astroism which is the largest religion in the game)
Cons:
-Not very active (Probably due to higher ranking players being busy in RL)
-Surrounded by allies (Have to travel far to fight enemies)
-Theocracy of Sanguis Astroism
-Banker title. Called Banker while other two positions are named after three important concepts of SA (Sword, Cup and Hand)
