scry_beforeTempting as it is to make millions, Adarin will not hike up the prices for most of his fruits. If this were something less necessary for people at his home, he'd jump on that in a heartbeat, but right now - he would like to prevent scurvy in the lower class. That comes first, despite how much good he could do with the money.
He hires several people to cultivate various fruits, marks out unclaimed land for them to be planted on, and hands out seeds to be grown. The results are promising. Unfortunately they don't grow instantly, they take time, but if there's one thing Adarin has, it's time. Not an infinite amount of it, but for something like this - he can wait.
Besides, he has several projects to work on, while he waits for trees to grow. A sewage system, proper waste disposal (he does not want a plague on his hands, not now, not ever), and making sure some streets are paved. All of these cost money to do, but Adarin's good with money, he's earned enough to pay for it. Unfortunately that's really more of a hands-off kind of project, he knows next to nothing about stoneshaping. Learning what he needs to know to be of any use would take longer than it would for ordinary people to manage it. Besides, he wants to give them jobs.
Luckily he has a project of his own to work on. Magic is endlessly fascinating, and when given a chance to study it - well, he's all for it. The translation spell is tricky, he doesn't just want to spell a book to be a dictionary and work from there, he wants the spell to be adaptable, flexible, and hidden. He's got enemies, and he doesn't like his things being stolen. So, if he plays his cards right - they might not even know there's anything to steal. It takes him several weeks, longer than he'd thought, but he manages it.
The results are better than he'd hoped. He didn't spell an object, he spelled himself. When he thinks about the winged man's language, grammar information and vocabulary unfolds in his mind. It takes some practice (all things do) but he adjusts well enough. There are few spells he can be truly proud of, most of them have little issues he'd like to work out, little problems that bother him endlessly.
This one, though, he is quite proud of.
With the language barrier out of the way - he can get so many questions answered. Things impossible to ask in mime and with little stone figurines and illusions. "How is he feeling?" "Is he lonely?" "What are the other species like?" "Where is his winged lizard thing?"
And, most importantly: "Will you help me?"
He wraps up several items of business that require it, and then one teleportation later, he is back on the island.
