After the destruction of Abagarlas, Endarre led a group of five Ayelid heroes: Curano, Lanath, Ostarand and Valasha on a quest to hide the Prismatic Crystal. They traveled to the Dwarven ruin of Mzeneldt in an attempt to hide the crystal. Curano, the Meridian priestess, was killed by Animunculi. The other four continued on. Lanath gave her life so that the remaining three could continue the journey. Valasha, having been mortally wounded, decided to give her life to relit the crystal, leaving only Ostarand and Endarre.
Following that, they hit a dead end as the following set of doors refused to open. He and Ostarand later figured out that the red crystals contained within the animunculi could power the crystals to open the doors. The constructs later broke through, and Endarre later wrote the last entry in his log dedicating his love to Lannessa. Endarre sacrificed his life defending against the animunculi so that Ostarand could hide the crystal in the deepest part of the ruins.
The five later remained as ghosts reenacting the quest they accomplished in the ruins.
Endarre and the other four heroes will be seen throughout the ruins reenacting their journey hundreds of years ago.
In a flashback, Endarre is seen tasking Ostarand with destroying the Mortuum Vivicus.
