After the Great Bombardment, many stalkers and pathfinders were lost due to Zone storms and shifts. The Kommissariat build Mayak (Lighthouse) Bunkers for people beyond the wall to seek shelter in. They now dot the landscape and provide safe havens for those who need it.
Concept for a personal IP called KOM-44. An alternative history where the Soviet Union becomes the Kommissariat (KOM) after bombs fall at the end of WWII. The KOM remains untouched and surrounded by an immense wall, but the rest of the world has become an immense exclusion zone filled with anomalies and land that defies time and physics.
