As far as I know, Eranikus is currently lists as as destination realm for high pop realms. So folks on those realms can transfer to it, but new characters cannot be created there unless you already have a character.

FROM TO DESTINATION TYPE Benediction Eranikus (NEW) PvP Benediction Old Blanchy Normal Grobbulus Eranikus (NEW) PvP Grobbulus Old Blanchy Normal Faerlina Eranikus (NEW) PvP Faerlina Old Blanchy Normal We strongly encourage players who wish to use a Free Character Transfer to do so as soon as possible. Free Character Transfers may be closed without warning.
