The Celestial Forge is the greatest combination of crafting powers in Jumpchain, meaning it is the greatest combination of crafting abilities in all of fiction. In Brockton Bay a forgotten side character's trigger event ends with him linked to the Celestial Forge rather than his intended shard. His expanding collection of tinker abilities drag him into the city's cape conflicts.

An alternate version of events that diverts from chapter 3 of Brockton's Celestial Forge. A connection to the world of Girl Genius sends Joe from Brockton Bay to Europa before the events of the Agatha Heterodyne and The Beetleburg Clank. Joe struggles to adjust to the new world while still managing his rapidly growing power. Updates will be less frequent than for the main work.
