Horus Heresy character series

[Tolmeus]

Since we kind of started "What is your best guess/wish/..."-topics, which character would you like to get a book in the Horus Heresy character series?
As a reminder, we got four books in this series so far:

• Legio Custodes - Constantin Valdor (Valdor - Birth of the Imperium by Chris Wraight 2020)
• Dark Angels - Luther (Luther - First of the Fallen by Gav Thorpe 2021)
• Imperial Fists - Sigismund (Sigismund - The Eternal Crusader by John French 2022)
• Emperors Children - Eidolon (Eidolon - The Auric Hammer by Marc Collins 2024)

 

A personally wish for me would be Hastur Sejanus for the Luna Wolves and a bit obvious, Sevatar for the Night Lords as well as Forrix for the Iron Warriors.

I can't think of a character for the Space Wolves though.
 

As an afterthought: We got zero books in 2023 and 2025, kind of a bummer when you have got 15 legions + different fractions (Mechanicum, Imperial Guard, ...) left.
