During the events of the Aranthian Succession, Lady Haera Helmawr became embroiled in a brutal civil war that began when her father - Lord Gerontius Helmawr - was left in critical condition by an assassination attempt.
The conflict that flooded in to fill the ensuing power vacuum wracked the planet, and Lady Haera - the de facto ruler of Necromunda while her father convalesces in stasis - was caught in the crossfire. She’d already killed off as many of her direct rivals for the throne as she could (in other words: her siblings), and when Lady Credo’s rebels came, Haera barely escaped with her life, encountering her brother Tamino at the gates to Hive Secundus. The story ended with the pair donning Spyrer suits before entering the dark and ruined hive.
Now she has resurfaced with a cutting-edge rig of her own and is prepared to terrorise the Underhells of this former prosperous hive during the next chapter of Necromunda.
