Pocyoh

An emerged Carkade Temple and palace complex that has emerged from the Time Void during the current Major Discontinuance Event. Located somewhere west of Semudan, Ruby Empire of Redin, the SRG took Dawn Eventide's comatose from to the the complex to remove the parasite Drana Intelligence from her. The exact events of what transpired are largely unknown, however ultimately:

the SRG were dispersed and seperated
Ophion Siabhaal ended up in the Time Void, only to emerge a few years later in the territory of the Blue Catar
Professor Ruben ended up in The Spaces
Heian of Liodan has been lost to The Spaces since, however his wolf Onai ended up being found by the Elves of Tarathiel
Kunoh whereabouts are unknown
Maybellina was rumoured to be rescued by her patron and now lives a shadowy life in the Feywild
Atala whereabouts are unknown
Tranquil Mind vanished with his Loxodon Pauldron en route to Pocyoh, whereabouts currently unknown

Many time voids have opened around former Carkade places that were used as a way of escaping, including in the vicinity of the Pocyoh Pyramid and Temple complex. It is ruled over by a fully fleshed, but still Undead Mummy Lord, Hunaphu of Iktani. She has undead Alin slaves serving her as she is assembling her army to be ready when called by the Carkade Emperor. Hunaphu of Iktani’s consort is Colopo. High Priest Kinto Kimil resides in a temple attached to the God Pyramid, always ascends to the peak when the Time Void opens.

Time Void
The Time Void appears at random times in the vicinity of the Pocyoh God Pyramid. The Moranth statues will always warn of the arrival of the Time Void. First the sky darkens, the sound of the time void rings out, the Katari serpent spirits emerge and then the void sweeps across the pyramid temple complex. Spirits and undead emerge slowly at first, but more and more quickly. The pattern can be determined by overlapping the Carkade astroplanar discs according the encrypted instructions of the astroplanar observatory.
