AGS ThunderFire

The AGS ThunderFire WAS an Absolvers Stormraven, that was used for worship and ceremonies. However, it was gunned down during the Aeran Crusade, and fell into the warp, never to be seen again.

Until Elfric stole it.

Tech-Marine Thunderfire
The Thunderfire is so called as it houses the Spirit of a techmarine known as Thunderfire.

Thunderfire was well known for his use of the Thunderfire Cannon, and his research into the Stormraven's weaponry.

The Arsenal of An Eldar
After Elfric took the Thunderfire when it fell into the warp, he decided to house it in Beil-Tan's hangars, in his own personal hangar, alongside a Necron Monolith, a Riptide and one of the last Imperial Jetbikes. He repainted it in Beil-Tan colours, added his name to the side, and repurposed it into a Command Gunship, not a fucking temple. He also took Thunderfire's Crypt, one of the most valued pieces of machinery the Absolvers had, and destroyed it, absorbing Thunderfire into the one of the 8 Soulstones he wears on his Belt. These stones power the Phoenix Gem: since the Phoenix Gem needs a lot of power to charge it, a soul sacrifice can be handy. Thunderfire joins the souls Appius of The Emperor's Fists, and Atholax, a Daemon Prince, as well as a Hive Tyrant's synapse presence, which he contained in a Soul-Stone.
