Situated beneath the Forgehearth District of Astraloftum, Tekkhead Labs is where Tekk-blessed inventors push the boundaries of technology. Sentient automatons serve as advisors and companions, and a deep network of tunnels exists where Gems are mined. Rival inventors vie for commissions from the Church and competitions are staged here. There are several clearance levels; what exactly happens in the deeper levels remains a closely guarded secret.

Vincent of Damocles owns an entire lab here - where he was secretly building the A.R.K and P-Sowen.
