On to the topic of the Shal’dorei, Light-Forged Draenei and other ‘glowy’ races, with couples, it can be something of a learning curve to learn to sleep in the same room, or even bed, with somebody who literally glows at all times.
On to a less meme-y one.
Shal’dorei don’t receive their runic tattoos until late adolescence, at which point their position in their society was made semi-permanent due as much to bloodline and social rank of their family as their own, individual abilities. It is why the higher-ranking Shal’dorei have runic tattoos that look like they were either assaulted by an army of ants that had run through a pool of glow-in-the-dark paint and concentrated liquid amphetamines immediately prior to said assault, or are the unholy love-child of an early 90’s Deviantart artist and an extremely ADHD tattooist.
Family rank, level of proficiency in the magical arts, proficiency in other areas, social rank and similar details are all etched into the skin with magical energy and, in the case of the ‘truly’ elite, perhaps even the tiniest trace of the Nightwell’s energy to further cement the connection between the individual and the Nightwell, hence why we see most Withered as mindless wretches, and yet the three primary NPCs who help us kick off the Shal’dorei Rebellion are also Withered and yet are able to maintain their consciousnesses and personalities due to a lingering, if miniscule, connection to the Nightwell via their runic tattoos.
Over time, as the individual rises and falls within their society, their runic tattoos might be changed and altered, depending upon the nature of their rise and/or fall, entire sections of the tattoos might be removed to ‘wipe away’ a disgrace, or to punish the individual by completely removing their successes and making them lower than even a menial servant. For the most part, however, you can tell a Shal’dorei’s entire life history based upon the size, complexity and runes contained within their tattoos, and that’s also why extremely high-ranked or ambitious Shal’dorei wear such revealing outfits, they’re boasting of their accomplishments and daring you to get close enough to literally bask in their presence just to get that information in the first place.
