The Original Sin

The Original Sin is the final raid of a fictional Invidere RPG, depicting the Outlanders' venture into the deepest pit of the Aether to confront the Ancient Fear, the allfather of creation bent on omnicide as retribution for the Titans' ultimate betrayal in the Before Time - the "Original Sin." 
==Background==
The Original Sin is unlocked by accepting the quest The End of it All from Gamma, located in the Shattered Shore region of the Aether. The raid pits the heroes against a series of three "boss" encounters culminating with the daemon-sultan himself. A total of 8 adventurers may be taken into the Original Sin, comprised of any combination of the possible remaining heroes:
*Ulysses (Paladin)
*Ned (Warrior)
*Amare (Rogue)
*Sam (Ranger)
*Ben (Black Mage)
*Jeremiah (Assassin)
*Manny (Alchemist)
*Josef (Lancer)
*Clockwork (Machinist)
*Storm (Bard)
*Gamma (Astrologian)
*Marc (Duelist)
*The Oracle (White Mage)
==Tier 1 - The Chaos Verge==
Having fought through the Shattered Shores and reached the highest point in the broken Aether, it's time to ascend to the Chrysalis, the allfather's home, by climbing one of the tentacles of his massive dormant original form which threatens to awaken at any moment. On the climb, the heroes will be met with an onslaught of the Ancient Fear's twisted minions whilst taking care not to be pelted into the void by flying debris generated by nearby black holes constantly funneling in matter harvested from parallel worlds. Atop the allfather's arm is the Chaos Verge, the gateway into the Chrysalis. It is guarded by Nyx, Moros' eldest daughter and one of his most formidable allies. As the "steward of the void" she is charged with defending her father's domain at any cost, making a confrontation inevitable.
==Tier 2 - The Chrysalis==
With the Night Mother defeated, the party proceeds into the allfather's gaping maw and heads towards the core in search of his avatar. In the darkness of his dormant form, each player must navigate through a personal maze filled with void abominations until the party reunites at the door of the Progeny Chamber. Within, the heroes must face the resurrected forms of three familiar descendants of Moros in their true forms individually until they form together as the true boss of the tier.
Throughout the confrontation, Fonts of Light and Fonts of Shadow will randomly manifest on the field, aspecting heroes toward the respective element should they accumulate three stacks of the same element. As Novrakosh and Heiroban are heavily aspected towards Light and Shadow respectively, attuning yourself to the opposite aspect is the only way to withstand their powerful attacks.
==Tier 3 - Nuclear Chaos==
Having weathered the devastating onslaught of the undead gods, the time has come to proceed into the Chrysalis' core, Nuclear Chaos. Here Moros himself slowly accumulates enough quintessence to break free from his temporary host, the body of Triton, and re-inhabit his massive true form that comprises the entire Chrysalis. The heroes must first defeat the husk of Triton, then withstand his transition state, and then finally face the fully formed Ancient Fear for the fate of Emanation.
