Tzirka

Tzirka are star-shaped artifacts able to trap individuals even of extreme power.

Description
Tzirka appear as large red jewels set in golden stars.

Lore
According to legend, Tzirka are artifacts of Feanor's design, able to trap even a god. They aided him in his final quest to perfect the Seeing Stones.

Qualities
After completing a 1 minute ritual, you may target an individual with a soul that can see Tzirka. The target is imprisoned inside Tzirka. Time ceases to flow for it, and it doesn't grow older. Nothing can pass through, even by means of teleportation or planar travel. The gemstone can’t be cut or broken while the spell remains in effect. You may only have one creature inside the gem at a time. If you complete the ritual again to target another individual, the imprisoned soul is released to a safe space within 30 ft. of you.
