A magical curse which isolated Fronela internally and externally.
- It was set in motion by Snodal to prevent an evil plan by Zzabur to sink Fronela.
- The curse was performed in 1499 ST when the Syndics killed the God of Silver Feet and mutilated its corpse.
- It isolated the communities of Fronela from each other.
- It was breached when Dormal opened the Oceans.
- The breach gradually lifted the Ban from Fronela, which is known as the Thaw.
