When I lived on the surface, I remember running through a field of daisies. They looked beautiful, I'd been cooped up in school all day.
As I rushed headlong through the gorgeous beauty of sun-drenched surface flowers my legs began to burn. I'd not seen the thousands of stinging biting wasps that pricked my legs. I spent the next weeks bed ridden and incapable of moving or playing.
Orison, you are running through a field of flowers. Do not urge Sewertown to follow. Lower Sanctuary can not exist, has not proven it will last. Until it can prove it has the power to repel the Spellguard and Watch, to keep the peace without tyranny, Sewertown is our home and where we must remain.
Your history books teach that Upper conquered Lower because it couldn't "protect" itself once before. The Tigereyes still patrol the streets, they've only changed their names and their "leaders" supposedly. The Seekers have always been optimistic, too optimistic. It is far too early to think Lower Sanctuary has been made safe.
It is a siren's call.
