Things that have occurred over time:
1. Jilitse and Stitch had a thread together related to this quest, found here: Always Darkest Before the Dawn. Jilitse was marked her level 1 Luminance Gnosis, and Stitch was invited to Taldera, somewhere in which the Order of Radiance's headquarters is located.
Jilitse is currently moving towards Yahebah (Eyktol) to search for Saghal Hrinn's (Sagallius) past, while Stitch is spending his lovely days in Avanthal (Taldera Region)
2. It seems that Torc Ironwood is also planning a player-driven quest to make Aquiras a new heart. No details yet.
So there are two options it seems, but for the most part I'm recruiting people who are not only interested in restoring Aquiras, but are also interested in defeating Sagallius.
Players who have shown interest in this quest are:
1. Stitch (Human) - a not-so-ordinary blind man who is also a follower of the Goddess with a past he couldn't seem to leave behind him
2. Fenilen (Inarta) - a devout follower of Priskil, has often repeated that the evil in this world must be purged.
3. Jabran (Chaktawe) - a follower of Priskil (gnosis mark underway) who was stirred in the desert to help the cause
4. Conrad (Human) - a follower of Aquiras who mentioned his interest in helping restore the heart of Aquiras
5. Kamalia Timandre (Konti) - A reimancer who personally aims to defeat Sagallius and become the goddess of magic
6. Ialari Pythone (Isur) - Is on Drainira's (Sagallius' champion) hit list. Will help bring down the Supervisor, but as to killing Sagallius, allegiance has yet to be determined.
