Thryges' obsidian vault

Place the obsidian shards in a loose circle around any non living objects or materials. After the shards are placed you draw transmographic glyphs over the pieces. Once the ritual is completed the objects are drawn into the largest of the shards, stored in an extra dimensional space. Items and materials don't age or decay whilst inside the shard. As a bonus action the name of an object can be used to withdraw an object from the shard. Items stored within the shards cannot exceed a total of 500 lbs.
