There's a common analogy made in tabletop fantasy games like D&D and Pathfinder, that Spells are like Guns and Spell Slots are like Ammo. And sometimes that Spell Level is like Calibre, and that Cantrips are like Sidearms, and that AOEs are like Explosions, and Cones of Effect are like Shotgun Pellet Spread, and that Short Rests are sorta-kinda like Reloading if you stand back and squint a lot, and Material Components are like, uh, bullets made of money? And Ritual Casting is like... uh... well, the analogy breaks down if you push it too far. BUT, the point is, Jon was about to discover he was in a game that had taken the firearm analogy and ran with it, and decided the best adaptation of TTRPG Magic cliches to video games was a Hero Shooter, an online Multiplayer FPS wherein Spells literally fired off like bullets at a crosshair. He found this out by being dropped on what seemed to be the literal front lines of whatever war it was that needed the titular Spellcasters.
And no, he didn't have the foggiest idea what the said Magic War was being fought over. After entering through the "Play Casual" double doors and picking a game mode (Jon kinda just picked one, the "Borderlands" game mode, at random) Jon abruptly lost his body and got sucked through the fucking Portal through spacetime that had been labelled with that gamemode, one which seemed built to very unsubtly disguise a loading screen, and his incorporeal essence was transported to the Map "where he was most needed" (ie. where there was slots available for more players). He got to choose whether he was playing for the White Knights or the Black Knights, interestingly, though he later learned this was because both teams had equal player counts at the moment and he would've been transported to the smaller team automatically if this weren't so. Only then did he get any sort of briefing about whatever it was he was actually doing, and things like Lore and Broader Context absolutely were not part of that briefing.
What he did learn a little bit about was the nature of his relationship to his Mistress. Apparently, Jon was now a Summon, a creature of the Astral Plane Conjured into the Material World as a disposable soldier bound to serve the Archwitch that summoned him. And the Archwitch, she... Jon didn't know if she was this land's Queen, or Empress, or Goddess, or some other Noble he couldn't comprehend, but she was the first thing he saw when summoned in, and instantly he knew she was very wealthy, very powerful, and very magical, and moreover that even thinking of disobeying her was a very bad idea.
For one, she was Beautiful. Unnaturally, absurdly, Sexy. There wasn't a part of her perfect body Jon's gaze couldn't get lost in. Her brilliant, knowing eyes... Her big, soft, billowing cleavage... her wide, plump hips on those creamy thighs... even her hair, her long, luscious silky hair, cascading straight down into picture-perfect curls at her perfect butt... If anything on her moved, he was hypnotized. When he first saw her, Jon would've whimpered if he had a body, and he was thankful he didn't, because he didn't know what shameful things he would do to it just thinking of her from then on, let alone being in her enthralling presence. Mistress had power over him now, real tangible power with just her body alone, never mind all the other circumstances.
For two, her dress. It was as intricate and ornate as anything royalty ever wore. Soft, silky fabric in a rich pure color flowed down her graceful body in all the right ways, revealing everything promising and hiding everything tantalizing, wrapping tight around her gorgeous waist and billowing out into a voluminous regal skirt around her legs. She was certainly dressed the part of royalty; it all looked like it cost more than the McMillan's mansion put together, even without the crown. And her crown...
For three, her crown. Jon knew the Wishing Stone when he saw it, and the Stone was the centerpiece Jewel of her big, opulent, all-ruling heavy crown. It, and what seemed to be numerous smaller magic gemstones were cut, polished, and inset in delicate metalwork encircling her head. Later, when Jon could think straight again, not a single one of his horny thoughts about his Mistress's power over him would change, because holy fuck, she had the Stone! In retrospect, it might literally have been magic power he sensed coming off her in her presence, crowned as she was with it.
Her instructions (and the rules of the game mode) were simple and direct: Secure the border between her and the enemy Archwitch's territory by capturing every leypoint in no-man's-land. Apparently there were at least two Archwitches, the White Archwitch and the Black Archwitch, which summoned the White Knights and the Black Knights respectively from safe points in no-man's-land (Jon later confirmed when he switched teams that yes, the Black Archwitch was just a palate swap of the White Archwitch, with raven hair and a dark dress where the latter had golden locks and neat white fabrics. She even had a copy of the Wishing Stone in her crown, and both were eternally staying out of the other's Wishing range). The leypoints were evidently springs of Magic Energy, and if Jon and his team captured these deeper in no-man's-land, then his Mistress could move further in safely and Summon him closer to the enemy border he was trying to secure, all in the hopeful goal of capturing the whole territory. Conversely, if the enemy team captured too many, then Mistress would have to move further back to safety, and eventually perhaps concede the Borderlands. "That would not do," thought Jon, almost deliriously horny.
So, with the quick tutorial over, Jon grabbed a Longbow and became the Ranger, then left his Mistress's base at the far side of the current borderlands map (Swiftriver, it was called?) and made his way to a leypoint in the middle of the map where the skirmishing was currently ongoing. Once there, Jon took a moment to come to grips with the fact that Ranger apparently didn't actually have arrows or bolts despite having both a big Longbow and a small crossbow, when a light shined in his eyes from a long ways off. Jon blinked a moment, and then his head was blown off by the enemy Ranger. Now incorporeal, he watched his dead body fall over and disappear from his ghostly vantage, along with the fading of the glowy trail left by the enemy Ranger's Magic Arrow spell. Mistress re-Summoned him back at the base a few seconds later and bid him try again, so he grabbed another Longbow and started heading back to that leypoint, but this time he didn't even make it that far, since apparently an enemy Ninja had flanked successfully and stabbed him in the back while he was walking. The enemy team had captured the middle leypoint before Mistress could Summon him again.
"... Maybe I need to back to Tutorials and Training first." He didn't wanna just abandon his Mistress, but...
