I nominated Astrid Dane and Athos Dane under Shades of Magic. Here are their wiki pages: http://schwab.wikia.com/wiki/Athos_Dane and http://schwab.wikia.com/wiki/Astrid_Dane

I nominated these characters under The Shadow Campaigns - Django Wexler:
- Marcus d'Ivoire
- Janus bet Vhalnich
- Raesinia Orboan
- Winter Ihernglass
- Cytomandiclea

Here's a post from the author's blog listing some characters (Marcus, Winter, Janus, and Raesinia) : http://djangowexler.com/2016/03/01/shadow-campaigns-ages/

As for Cytomandiclea, Googling her (very uncommon) name will probably yield good results. She's also mentioned on the series' TVtropes page, if that's helpful? http://tvtropes.org/pmwiki/pmwiki.php/Literature/TheShadowCampaigns
