Hmm, I'll think about this, then. What do you have in mind? Delta, same question to you.
I pretty much planned for Safiyyah to get into some sort of exclusive event or something to meet with Arsenikos. Perhaps a pre-planned victory celebration for the returning emperor? She might very well be the only Iiramite in Arachnae, so I figure she'd be let invited by someone of fair status due to being interesting and "exotic."
Alternatively, once she learns about Arsenikos, it's possible she could go and offer her services to him in return for his help in finding the Philosopher's Stone. Or... maybe he hears about her and decides he could use an alchemist?
