Translux Candle

Wondrous item, very rare
  Translux candlewax is refined from the rendered fat of planes-travelling beings. Poured in the center of a permanent teleportation circle under the light of the stars. the candle becomes locked to that teleportation circle.
  When found, a translux candle has 2d4 + 2 charges.
  As an action, you can light the candle, expending 1 charge and causing it to cast a dim, purple light in a 10-foot-radius sphere. This light slowly brightens over the course of a minute. At the end of the minute, an eruption of glowing purple sigils forms a teleportation circle in the lit area. The circle appears on initiative 20 of the 10th round after the candle was lit and lasts until initiative 20 of the following round.
  Each creature in the area when the circle forms, or that moves into the area while the circle is active, is teleported to the destination teleportation circle where the candle was crafted. When the teleportation circle ends, the candle also teleports to the destination circle. A creature can use its action to snuff out a candle within its reach that isn’t being held by another creature. If the candle is held by another creature, the creature trying to snuff out the candle must succeed on a Strength (Athletics) or Dexterity (Sleight of Hand) check contested by the holding creature’s Strength (Athletics) or Dexterity (Acrobatics). If the candle is snuffed out before the minute elapses, the teleportation circle never forms, and any expended charges are wasted.
