Toma set his clipboard on the table and leaned forward slightly, excited about explaining something he genuinely enjoys.
"So. Gates," he started. "Most people treat this like background knowledge but honestly it's the most important thing an Exterminator can understand, because the type of gate determines everything — how you go in, how it ends, and whether it ends at all."
He held up one finger. "There are three types of gates that commonly exist in out world."
"One-Way Gates. These are the most common and the most dangerous for civilians. They open on their own without warnings. Out of these, calamity Beasts pour out from the other side. You cannot enter them from this side. The only way to close one is to fight through the waves of monster and find the Gate Guardian and kill it. Once the Guardian is dead, the gate collapses." He paused. "These are the ones that cause urban incidents."
He moved on before Hide could react to that.
