Ashbringer: There is a miniatures Bael'Zharon statue in Nanto that allows only PK's and PK Lites to enter... inside is a bit of walkway tunnels and then a middle room that appears to be a Mansion basement. New PK fun!
Little tip, the ring of fire is not what it seems!

EpicFX: Was portaled in by the statue (used PKL). After exploring a little, logged out and back in, got a timer message by the statue. Looks like a 25 minute timer for heading in, which may be able to be passed w/ the correct bribe to the statue
