Starting when you choose this origin at 1st level, you can use a bonus action to summon a 5-foot diameter glyph on a surface you can see within 30 feet of you. The glyph is visibly magical, radiating dim light out to 5 feet.   While within 30 feet of a glyph, you can cast sorcerer spells through it as though you were in a space in its area, though you must use your own senses. If a friendly creature is in a glyph's area, you can make any spell you cast through the glyph that targets only you instead target that creature. You must maintain concentration on the spell as normal.   A glyph disappears after 1 hour. It disappears early if you summon a new glyph, if you dismiss it (no action required), if you are knocked unconscious, or if surface the glyph is summoned on is moved.
