So, he does the obvious thing. He outsources. He's not the only mage in the world, not even close, and he just so happens to be extremely rich. He asks (well, asks and then pays) a talented stoneshaper to make the necklaces in one fell swoop, and then spends several hours bugging significantly less busy mage healers at hospitals to make the portals. He only manages to get three sets, but he deems this 'better than nothing.' Especially considering most mages don't have a strong enough bloodline to manage a portal on their own. Just three was difficult to get, and required a lot of teamwork.
With that done, he heads off to Perinixu's temple, to shower Spring with gifts. In the sense that he will hand them to her, and then ask her nicely to use them to heal people.
Spring is at the temple, right on schedule, doing various errands involving putting on a good face for the very first interactions of Perinixu with her new planet.
"For me, or Perinixu?" Since this is where one would bring presents for Perinixu.
"... Yes? Both. I don't know, is there any change in if I put the magic portal necklaces onto the altar, or just hand them to you?"
"Well, in the one case, it's for me, and in the other case, it's for her. The magic portal necklace is probably for me. Gaming the system by giving acolytes useful things 'through' our deities is generally frowned on."
Six portal necklaces go to Spring. Only three sets of portals in total, but that's three more than they had originally.
"Excellent, now I'll be able to be in more places at once." She collects them and then turns around and hands half of one set to the priest she has manning this site.
"You're welcome," he says, in a cheerful tone. "I'll be able to make more, or have more made, but mages need to recover mana."
"Good, if you didn't I'd have to try to explain it again more slowly, and there lies the path of sorrow and torment."
She spots Prime.
"You!"
"You get a prize. Congrats. Now! You!" She points at Prime. "You did this, didn't you!"
"I do lots of things. You're going to have to narrow it down..."
"Oh, fuck you, you know exactly what I'm talking about." She motions around them, to the temple. "This shit! This fucking shit! What the fuck is this?!"
"You let her in," she says, in a deadpan. She looks at Prime. "What. The fuck. Other planes?! Really?!"
"Okay, take your fucking smarmy attitude and shove it up your ass, you hypocrite, I don't believe you, you asshole!"
"He didn't - some friends of mine came to visit him and later introduced us," summarizes Aya. "That's all."
"Visit him. Visit him?! Why the hell would anyone visit him?!"
