Balmus Coldfront's Widget of Phantasms

Thousands of years ago, the Tieflings believed that they had brought the nebula in space inhabited by dwarfs completely under their heel.  They had, it turned out, brought all the planets but one to heel, the dwarf's home world; Mandragon.  Mandragon is a bastion for dragons, and the dwarfs and dragons flourished in a system of symbiosis.  The dragons would help dwarfs in their excavations and the dwarfs would keep them safe for their sometimes centuries-long periods of hibernation.   The dragons helped teach the dwarfs technologies and skills they otherwise wouldn't, and over the years, this led to the dwarfs reaching out to the planets around their homeworld. Although they never communicated it, the dragons, all along, were creating a buffer zone so that they could have the advance notice to go dark upon the dwarfs' civilization's inevitable discovery by the Tieflings.  When the Tieflings first invaded the nebula, the dragons cast a spell on the entire planet of Mandragon, wrapping it in an unassuming hologram of the space around it. It still orbits its star and sunlight still reaches it, but it is undetectable to the outside world.  In the very bowels of the Blue Dragon organization is a portal, the single opening to Mandragon, where you have been several times on quests for your organization. 

Although never as adroit as the dragons with spellcasting, a genius tinker created holographic devices hundreds of years ago that utilize the same powers and can create the same effects as Mandragon's hologram, although on a much smaller scale. 

The widget has three uses before it needs to be recharged. It can be recharged with 1 dragon canister (1/10 of the larger Dragon Canister).

When active, the Widget will work for 10 minutes (or up to 30 minutes continuously if you use a full charge all in one go). It requires an ACTION to activate and requires your concentration.
