an old time miner's lantern
An oil burning miner’s lantern.
… In 1753, a small group of scientists at Kingsport College discovered that the light produced by burning whale oil in a miner’s lantern had properties that assisted the closure of dimensional rifts. However, when they tried to reproduce the experiments, only one specific lantern worked to produce the light necessary to close the rift.
The beam of light generated by this lantern will close an open dimensional rift.
