Permanent Spell

The strange energy shown by the "door" could not be detected by normal means, yet it was truly affecting the physical realm.

Angor had spent a long time in the strange dimension he was taken to, but he still couldn't tell the exact nature of the energy. Though he did know that he should not put the opportunity to waste.

There was a second reason why he wished to keep the spell model in his mind space longer. Usually, once the model of a spell or cantrip was successfully made, it was either spent when the spell or cantrip was cast or disappeared on itself when the caster did not support it. It could not be kept in one's mind space.

But there was an exception. A "spell slot" was used for permanently printing a model onto one's spirit.
