Bombshell Genius
The Petranaki Arena before it became a Force-nexus (22 BBY)
Image source: Attack of the Clones
Name: Stalgasin Memorial Stadium
Planet: Geonosis
Nexus Alignment: Dark
Nexus Effects: The effects of the nexus on people going inside Stalgasin, and especially its central playing surface, are pretty straightforward: for many, its effects include feelings of being dazed and confused, and sometimes fear and paranoia. Also you can use Force-powers using less energy than you would normally need, especially when dark-sided powers are in use. However, light-sided powers require more energy.

Description: The Stalgasin Memorial Stadium floor was mostly sand and slit, with the lower walls being engravings and bas-reliefs of famous battles and events. A large tunnel connected the arena with underground droid factories and was located below the Geonosian High Audience Chamber. It contained seating for over 100,000 spectators, whereby the upper Geonosian classes, as well as wealthy non-Geonosian patrons, would watch on the lower seating levels. On the lower walls are gates where acklay-sized props can be brought in or out of the playing field.
Origins/History: The Stalgasin Memorial Stadium was first built in a natural formation carved out by millenia (or even millions of years) of weathering, with Geonosian additions over the centuries. The Petranaki Arena is most famous for having been the location where the Clone Wars started, where roughly 180 Jedi were killed in 22 BBY within its premises in an attempt to rescue Obi-Wan Kenobi, his Padawan Anakin Skywalker and his then-future wife Padmé. In the wake of the two Battles of Geonosis, it took serious damage. The loss of so many light-siders in so short a time built a foundation for the later dark-sided contributions of the nexus caused by the Sterilization of Geonosis, causing a major disturbance in the Force. Hence the nexus being dark-sided.
For centuries, the stadium was damaged with the different factions holding the planet not having an interest in repairing the stadium back to its former glory. As Geonosis was repopulated, based on the offspring of fertile queens stashed off-world by the Confederacy and Separatist holdouts at the end of the Clone Wars, by 240 ABY, the Stalgasin Hive, who owned the premises during the Clone Wars, and even to this day, decided to rename the Petranaki Arena as the Stalgasin Memorial Stadium, in memory of its role in the early stages of the Clone Wars. Also, it took about 30 years to rebuild. It saw little use during the Gulag Plague by virtue of the public health hazards caused by mass entertainment of that variety. It is nowadays controlled by the Techno Empire.
Intent: To provide the Techno Empire with a Force-nexus, and also to provide additional lore beyond the canon on a canonical location
