Since yukie1013 may want a bit of babble.
It got to be a joke with the two of them. Part of it was that - well - in Leander's case, he'd gone off to the crusades thinking that he was fighting for God and country and he wanted to see something other than his small town. Also, the governer had promised three hundered ablebodied men, and he was old enough.
His dad joked with him about telling him if he found any interesting magic. Or mystical lore. He worked as an alchemist. At the time, it was for a minor Count. That changed of course. His dad was more interested in scholarship than currying a good patron.
And he kept odd friends. Of course, part of it was that the Finnish branch of their family had their own connections so they'd tend to get odd guests showing up at the house. They still used the Vainula family name, and they talked late into the night.
The chaplain said that his father was courting the devil and that Leander was lucky to be saved from that unholy house. The chaplain said a lot of things. The fact that Leander swore that he heard voices from furniture didn't go over well at all.
That's why Leander liked Daniel so much. Daniel was someone who didn't care. Leander said that he heard voices, Daniel said that he thought this Allah thing was little different from their own religion - and - it was all right. And he was right. The more he heard of Islam, the more that he thought that this fighting to kill the infidels was ridiculous.
It got to be a joke. They'd gone to the Holy Land. They'd gone native. Didn't that mean they'd become more holy?
Leander made his money by a bit of smithing and writing for his dad. He'd picked up the knack of understanding enchantments on weapons while they were stationed for a while. Uncursing a blade wasn't easy, but it paid well when the case came up. Scholarship tended to be a late night job. Partially due to the fact that some people though that books carried the devil in them, and mostly due to the fact that Anna's kids tended to be small whirlwinds of distraction.
He wasn't living with Daniel, but he was close enough that they visited a lot. It was a quiet town that didn't ask too many questions about his books or his motives. Considering that some places burned you if you were too good with herbs, it was good enough.
Daniel said he was a medic, which was inaccurate, but true enough. Alchemists tended to kill themselves via playing with mercury and arsenic in the wrong proportions even when they didn't wake a mob hunting to stop them from doing strange things in their homes.
Sometimes, if Daniel's knee wasn't hurting too much, they'd go on quests for his dad. They found limestone pebbles near the Pyrrenes. They gathered amethyst from the Rhine for an experiment. And it was - mostly pleasant enough.
When his dad asked him to find Hangman's Sedge from Wallachia, it sounded like the usual sort of job. Some remote area, a random herb that sold for too much on the market, and a simple procedure to find it.
