Hi hi pixelrhys again do you have any fun AUs for your Terraria guys because I'm looking at you with big eyes. Do you ever consider making some if you don't have any?
This ended up rather long as I went into a big infodump, so I’m gonna toss it all under the cut!
Kinda yes, kinda no! It depends on how loosely you define AU -- Chris and Andrew (and sometimes others) occasionally get thrown into other things I’m doing, but I don’t have many actually-thought-out AUs of Purity Town proper. PT does have a sort of "levels of canon" thing going on such that the more self-indulgent ideas I have aren't really canon but are just for fun for myself, but none of them are fleshed out enough that they've gone beyond a one-off doodle here or there. (That category mostly consists of random ship stuff, fun character interactions like various characters being a part of the Lunatic Cult, indulgent fun with Chris' powers/power level and star theme, fun with Andrew's personal powers, and so on.) Things that don't go beyond a one-sentence idea, essentially. That also includes a lot of wildly differing post-game ideas that haven't yet been ironed out, though admittedly I haven't even posted most of the ideas I've had for hardmode, so that doesn't count for much.
Chris, Andrew, Alalia (the Dryad), and the Lunatic Cultist (kind of -- name irrelevant, roughly the same character) all appear as NPCs in a D&D setting I’ve been working on and off for a couple years now. The simple background of the setting as it relates to them specifically is that an age ago a civilization of arcane casters (“Ascendants”) inhabited a giant crystal cluster that grew after a star fell to earth, but all disappeared in an instant with the coming of a new god that replaced the sky. Chris, Andrew, and the LC were members of this civilization. Andrew was a Watcher, a unique role among the Ascendants for those with expertise in divination magic that allowed them to monitor the goings-on of their kingdom, a job that required a uniquely strong sense of self and strong discipline to avoid being swept away in the tide of information. Due to this quality, he was approached by the LC as a participant in a project to elevate a mortal soul into artificial godhood, but this initial attempt somewhat-failed as Andrew clawed his eyes out (and then refused any magical restoration) to reduce the amount of sensory overload his newfound godhood imparted on him. The LC also approached Chris to join them in a follow-up experiment, but he declined because he thought their research was bullshit (it was based on the true theory that reality, magic, mortal souls, and the souls of gods are all made up of the same fundamental material called Waver, but he didn’t think they had the technology to manipulate it in such a way). Chris instead worked on his own research, basically an in-universe equivalent of astrophysics-but-for-magic, studying how their world’s binary-planet (a gas dwarf named Sigil) and moon (a much smaller moon named Luna) influenced local spellcasting. When the LC’s next experiment killed every remaining Ascendant by ripping their souls from their bodies and forming them into a single light in the sky, Andrew survived due to the aforementioned partial-godhood and Chris survived due to working in a magic-insulated lab, and both were rendered unable to die as their souls were permanently bound to their bodies. Between then and the present day/start of the campaign after the crystal has been re-settled over centuries by non-Ascendants (forming the city/state of Lighthaven/Newveil), Chris starts a wizard school under the title of Wishmaster Delha, makes a magical crown to place a new king on the throne, fakes his death, and nowadays just hangs out selling potions to foolish adventurers. Andrew, on the other hand, started a mostly made-up religion around the new sky before dipping out of the spotlight and in the present day lives with Chris, helping him with his potions where able. Alalia is also present in the setting as the elvish-archdruid (i.e. not immortal but very very long-lived) leader of a druid community who oversees most of the area’s crops and natural trade goods of the area, and hates Chris/Andrew partially for being immortals, partially for being Ascendants, and partially because Chris keeps selling questionable not-druid-approved potions on the black market solely to piss her off.
Chris is also my player character for a Drakkenheim campaign (and Andrew is kinda there too)! The TL;DR of Drakkenheim is that 15 years prior to the start of the campaign, an eldritch meteor fell from the sky and hit the city of Drakkenheim, destroying much of the city and leaving the rest blanketed in a contaminating Haze, transforming the dead into monsters and making magic within the bounds of the city go haywire. In this setting, Chris is a human fighter (eldritch knight) who is mageborn (i.e. has the gene that makes people capable of channeling wizard/sorcerer magic -- relevant because mageborns have additional social-legal restrictions placed upon them due to the continent once being ruled by evil sorcerer kings and the fear of that happening again). Because of his weak magical ability and having grown up in the countryside and then having to move due to the spreading corruption as a refugee following the meteor, he missed out on being tested by the Amethyst Academy for magic and so didn’t learn about his powers until adulthood. He then had a very short stint at the Amethyst Academy before being kicked out for lack of ability, and over the next few years moved back in with his parents, met Andrew, learned another language, taught himself sword fighting, and decided to head to Drakkenheim to work as an adventurer for money and on the side try to research a way to control and eventually contain/destroy the spreading contamination that had destroyed his childhood home, while also trying to grow his own magical abilities. Kind of awkwardly, the Amethyst Academy mage NPCs tend to ignore his existence and belittle him, sole exception being his ex-teacher/ex-Academy-mage Ryan Greymere who’s also working to cleanse the city. Chris in this setting is also mildly religious (in a "it doesn't matter if it's inherently true to the world or if it gained power through people believing in it because in the end it exists and I grew up with it" kind of way), following a religion that instead of believing in a god like many of the old nature religions believes in a light of goodness inside of people. This puts him in an even more uncomfortable spot as the first paladins of this religion were renowned for freeing the continent from the ancient sorcerer kings, and thus said religion is the cause of a lot of the anti-mageborn movements floating around and the source of some nasty comments. Compared to some of the other party members (including but not limited to possibly the last surviving legitimate heir to the throne of Drakkenheim), Chris is very much meant to be Just Some Guy, but is super loyal and very ride or die as far as his relationship with the rest of the party goes (and unlike his first adventuring party, they didn't abandon him, so even better). Which is all good, because he’s not making much money from this, but instead got wrapped up in a plot to put his party member on the throne with hopes of using its power to restore the city. Andrew is kind of also present in this setting in that he’s an elven cleric of the same religion Chris follows, and is my backup character if Chris is killed. He’s Chris’ partner, and stayed with Chris’ family after Chris went off to start an adventuring career in Drakkenheim, giving him an excuse to join the party if Chris dies.
I haven’t posted much about the D&D setting I’ve been working on, but I’ll occasionally post Drakkenheim doodles when I have the energy to draw. Sometimes they include other party members, and sometimes it just sneaks into more generic Chris-as-a-character posts, as without specifically drawing his armor/scarring/party members it’s hard to distinguish his Drakkenheim design from his Terraria one. With the armor and scarring it comes off closer to his hardmode design, but as mentioned, I haven’t posted much hardmode content so that’s pretty irrelevant haha. And then as for all of the assorted self-indulgent one-off ideas, I just often don't feel up to drawing them, so they get to live in my brain rent-free instead, haha.
