HGS Matias Sobaseki (NPC structures Large Collidable Object)

Caldari State Workers Union Day is one of the few universal holidays mandated by the Caldari Executive Panel across all regions, territories and holdings of the corporate state. The day is the highlight of the CEP's State Workers Union calendar, with its corporate affiliate workers organizations all running a variety of celebrations and events over the course of the holiday. Often extended over a weekend, the occasion is a convenient time for the CEP's "Big 8" megacorps to hold their annual State Industrial Planning Summit.

One particularly popular event, watched by billions over the corporate holonet channels, is the Haadoken Summit of megacorp security forces and its associated Security Training Games. For some years now the event has been held alongside the Workers Union Day. Kaalakiota's Home Guard security force is a highly professional corporate military with many veterans of the Caldari Navy in its ranks and often scores highly. Their Workers Union Day parade fleet is led by the Leviathan-class HGS Matias Sobaseki, named for the Kaalakiota CEO who played a key role in the secession of the Caldari from the Gallente Federation.
