The Gammadion Cross, aka swastika or fylfot. A symbol that dates to an unknown origin due to it's mass usage. These crosses can be found in ancient architecture accross the globe. It was last used in the late 19th to early 20th century before being fouled by the Nazi era. However it's Hindu counterpart is still celebrated by followers of that religion.

There are currently pro-swastika groups that seek to resurrect the pre-nazi era love and usage of this symbol.

While Rule 86.a prohibits the use of the Gammadion in public, there are loopholes to this law. The Gammadion CAN be used in public as long as it is made clear that its use has no ties to pro-nazi meaning.
