Zomp Line

One of the colored subway lines in the Iron Tangle network.

Zomp Line debuts in book 3 as one of the vividly colored subway routes threading through the Iron Tangle, a sprawling transit dungeon that forces crawlers to master its shifting lines and stations. What begins as a simple navigational choice quickly becomes a high-stakes artery of the level, where color-coded trains, platform hazards, and rival factions converge. Across its limited appearances the line evolves from background infrastructure into a strategic battleground whose control can determine who reaches the next floor.
