Scientific achievement
The foremost scientists of the Aenorian Empire activate their greatest creation, a mechanical tower that will blanket the known world in their choking pheremones and thus enslave all sentient life in the world so that the rule of the Aenorian Empire will be made eternal. With its activation, hope is killed forever as almost all life becomes mindlessly enslaved to the High Lamia. Only a select few races are powerful enough to resist its influence, like the Titans, the Ancient Dragons, and a rare few others.
