What do the Fuzzes think of the god's mortal champions? Typhus, Lucius, Ahriman and Kharn?
Oh, this is interesting! Thank you for a question c: I will do them in pairs based on a deity since this is who would interact the most.
As per usual, a lot of it is in relation to what is "canon" in Fuzzverse, so, folks, don't go after my butt for making a cadaver from canon.
So, Lacedrace respects Ahriman from the professional standpoint and is drawn to his grand designs and dreams of restoring the legion, due to this often happy to drop by to work on something together. Somewhat managed to make the falling out between him and Magnus in regards to Rubric less volatile and made this a bit of a shared project between them to unscrew it.
An'Hangra and Kharn... Well, as it was mentioned earlier, she collects posters of famous warriors of the galaxy and has a signed one from him, so it gives some perspective. She does look up to him in terms of how formidable he is as a warrior. The closest thing I can really think of is really gym buddies. Her personal beef with Erebus, save for him being a very dishonorable bastard, is actually because he murdered Argel Tal, with whom Kharn was good friends.
Shanakay and Lucius are... Well, take one person obsessed with being a perfect swordsman and who can back the talk and take one daemon obsessed with perfecting all and every skill to be found and you get perfect sparring partners. On points of other forms of art or the importance of perfecting crotcheting and salad-making, they agree less. Does warp dust go in the salad and in what amount? A good question to fight it out.
Balthrag and Typhus do meet quite rare as I can hardly imagine him going out of the way to find her corner of Garden, but she herself I bet thinks of him in a moderately familiarly kind way, if it makes sense? They are all children and grandchildren to Papa Nurgle, after all. Some are rowdier than others. Also, I must admit I don't yet know enough about Typhus myself to make a call.
