• Codex Aeldari contains Drukhari units who can be used with Ynnari. Leaks suggest that this is Kabalities, Wyches and Incubi only.
• Disparate Paths is "include Harlequins and Ynnari, even though they're not Aeldari". You cannot select Ynnari or Harlequins as your Faction.
• Harlequins it seems will be limited to one of each character. So only one Death jester, etc. The exceptions is their own specific detachment, in which you can have three.
• You can take any Aeldari units you want in the Harlequins detachment. Nothing on Drukhari.
• No note in the article on whether Harlequins allying with Drukhari armies is still allowed (Travelling Players).
