Is the process of Lightforging directly related to faith? Can an individual be chosen to undergo the trials if they are less-than-faithful but are great combatants?
Note this is based on my inferance of the Army of Light. Becoming Lightforged is part of the Army of Light. Though there isn’t something that says pure faith in the Light is a requirement, it is insinuated heavily. Xera and Turalyon are huge parts of the AoL. Personally, if you are not pledged wholly to the Light, then I have doubts you’ll get very high in their rankings enough to reach the Lightforged trial. Could you go along with things and feign that level of fervor for the Light? Probably. You could channel your faith in something else as if it was faith in the Light. However, the Army of Light strikes me as an almost fanatical organization. But, we have no absolute lore either way.
Assuming a Lightforged Draenei and a Void Elf made physical contact what exactly would the effect be? Pain? Mild discomfort?
The Light and the Void are antonyms of each other. Most concensus is that a void elf using the Light would find it painful. Both beings are infused with the elements, so it would make sense that the opposing element would clash when in contact, causing some level of discomfort. HOWEVER… touching, caressing, kissing, etc are all probably fine. The forces are within the individual, not coating them. Turalyon and Alleria still have a relationship, despite their opposing forces, however they do still feel pain when touching.
Aside from Jed’hin what exactly would Lightforged Draenei have done to blow off steam. Alcohol was likely considered contraband but is it also likely a few would’ve been able to sneak bottles for celebratory times? Was there any time for romance among the Lightforged?
A very individual question. There is no stated lore that alcohol was contraband, so it really depends on how you want to take it. Turalyon and Alleria are still a couple, so I am sure there was time to get cozy with each other within the AoL. I could see one taking passion in a sort of profession hobby, like blacksmithing. Jed’hin is the only canon thing, but an individual would have individualized ways to relax. Writing, drawing, reading, exercise, meditation, blacksmithing, gemcrafting, etc. Being on Argus or in space for a while (time is hard to tell in the nether), hobbies would be dependant on supplies.
What are the benefits to undergoing the forging process? Are Lightforged individuals faster, stronger, or inherently better than other combatants? Is it merely to improve resistances to the fel and void?
They are more intuned with the Light and can more readily call upon its powers. More resistant to the Void and Fel. Inherently better is hard to say, but they would probably be better at Light based magics. Even classes normally without Light magic has access to some. Actual benefits depend on the individual and are unclear from Blizzard, but they seem to be immortal… granted draenei were already practically ageless to begin with.
If the Army of Light has been fighting since Argus fell, roughly 25k years before current events, wouldn’t it be highly unlikely for a player Lightforged to be exceptionally old? If so then did these pockets of Draenei reproduce during the war?
Based on the unlocking and intro quests, it appears that the Army of Light is increasing its ranks of Lightforged. That means you could potentially have an Azerothian draenei join, prove themselves, and undergo the trial. So, any adult age goes really. We have no evidence that they reproduced, though they could have. It is unclear, though they are devoted wholly to fighting the Legion and battle for the Light so child rearing was likely not a thought. Bird and the Bees though… so I don’t think it would be impossible. Does Lightforging sterilize? Not a clue.
I imagine the Lightforged as a Light Faith based draenei turned up to 15 with a military mix as well. Personally. However like all races and classes, each is an individual so variance will happen.
