the server AnimaRO was split(unwillingly) two years ago due to one of the gm's performing mutiny and copied the entire server onto a host he had set up, and that is called TalonRO now.(He changed all pw's to 12345 on aRO, causing total chaos and dropping 10+ stuff in prontera I think).
AnimaRO then closed down without any notice, and after a while it went up again as AnthemRO. They are going strong and it's one of the best servers in terms of donations, they rake up more then most servers combined in a month.
Example; Kafra Clips(a version of the kafra cards), where equipping and un-equipping pulls up your kafra storage. The price? 50$.
TalonRO is a normal server with normal donations, less expensive super lord kaho horns(+20 to all stats), it costing 60$or something on tRO, while on aRO it's 100$.
AnthemRO now has around 500 players I think, and TalonRO has max 125 during woe.
Both of the servers have SQI items, so that makes them special but it's seriously unbalanced.
