Don't worry, Zelda will rescue as much of Azmuth's stuff as she can. At least certain hoarders won't be interested in his research notes. (Is his home/lab big enough for her to get into?) I will have to go back through Azmuth's posts and think about how Zelda would continue his research because this sounds like a fun angle to explore. And if you ultimately decide to bring him back, then all the better!

...NGL That kinda gives me the idea of her mistaking Alastor for a noctaere 🤔 She's getting involved in anti-noctaere research with the goal of developing potions/medicine that could be used against them.
