Otto Frank's Star of David

Origin
During the tradgedy of WWII, many Jewish families went into hiding to escape death or the horror of concentration camps. The most famous is the Frank family, due to the publication of the diary of Anne Frank, the youngest daughter of the Franks. In an effort to escape the Nazi invaderts, the Frank family and some friends and neighbours hid in a concealed attic space, where they lived for two years.

Otto Frank, the family patriach was the sole survivor of the family, but his efforts ensured that his daughter Anne's diary was published so the world could know of their suffering.

The Star of David he willingly gave to Warehouse agents in the 50's was created by fear and hope, emitted by the struggling families throughout the war. It is carved into a wooden board, but it has since been modified into a wall hanging. Wether it was Otto himself who carved the Star into the woodwork is not known, but as he knew of it's power, he is attributed it's creation for filing purposes.

Effects
When the Star is hung on the inside of a door, no extrenal force can see or hear anything going on behind it. Looking through glass of holes in the surface will show an empty room, and opening the door itself will reveal nothing. The hidden person/s are not intangable, however, and can still be physically interacted with.
