This simple metallic ring radiates palpable
magical energy. It is adorned with a single red
ruby secured within a translucent crystal seal.
The crystal itself is adorned with a tiny
hieroglyph, conveying the concept of returning.
You can use an action to break the crystal seal
and thus cast the Gate spell with it, opening a
portal to the predestined place enchanted into the
ring. After one such use the ring lose its
enchantment and becomes a simple metallic ring.
