[That... is not an ordinary pillar.]
Endevil sounded grave and cautious. The voice added to retreat to the woods.
Perplexed, Adam could only obey the commands.
'What do you mean it's not an ordinary pillar?'
[That is a Solitude Seal.]
The new term was strange to Adam but he can tell that it didn't mean anything good.
[The Solitude Seal is an extremely powerful spell that can seal off anything for a definite amount of time. The spell manifests into a tangible form that isolates the subject in a sub-space dimension.]
'What does it have to do with retreating back to the woods?'
[The seal is not a rigid spell. It can be altered to fit the purpose and the intention of sealing. From simple spatial freezing to hellish torture, the flow of time can also be reconstructed. Fundamentally, it is impossible to know what is sealed inside the spell once it's set up.
