The Rift Gate name Cyseal East is incorrect. The gate is actually located just west of the Rank Tunnel exit (Ahru's Failed Experiment quest location), south of the Statue Gate, and just east of the beach for the Cecil's Mighty Staff (Deimiter) quest.
Cyseal Northwest, actually. Cyseal West should be the name of the gate which should be placed nearish the lighthouse.
Cyseal Beach East is another wrong name, because it is located in the woods/cliff in the southeast and not on a beach at all. Should be plain old Cyseal East
Actually, I think we're both wrong. After thinking about it and finding the path that leads North, (I assume to Silverglenn and additional map locations), what is NW now won't be when the full game is finally released.
