Requirements:
Must not have Mark of Hecatomb. Must have Mark of Knowledge. Must have Mark of Wisdom.
Assist a Beltan priest in his arduous quest.
'Travel the continent, and kill the Cruelty of Miannas, Beltane Altaar, Yourban, Jihulynth the taskmaster, the criminal leader, and the Kraken.' a cleric says to you. If its like hecatomb you have 60 irl minutes to complete this.
Might be once per reboot, must trigger the priest in recall (don't know how, but might be just walking in.) His task relates to killing a bunch of NPCs on Beltane, supposedly an absurd number in a short period of time.
