One of the brave Hellrider troops who charged into Yeenoghu's portal during the Charge of the Hellriders and subsequently fought at the Battle of Avernus.

Despite soem of the other Hellriders like Sven Lyons breaking faith and retreating back through the portal, Finnen stood alongside others like Edmond, sworn to stand strong with Zariel against the tides of darkness, no matter the cost, even after witnessing the terrible loss of life such as his friend Morgan die in his arms.
