Sonne Island is covered in snow and is home to a large forest; a large mountain is located in the center of the island, with its peak reaching approximately 837 meters above sea level. Due to the Ulysses Impact Event, the island is dotted with numerous impact craters–including the Antenora Crater.
Ulysses planetfall and aftermath
Following the announcement of the Ulysses 1994XF04 asteroid's increased impact radius, Estovakia began construction on its own meteorite interception system—Chandelier—nearby the island. However, with little over a year remaining before impact, it was not completed in time, and soon after, numerous asteroid fragments would fall across Anea. Sonne Island itself was also struck by multiple fragments, creating the Antenora Crater and additional smaller ones.
On April 1, 2016, the Republic of Emmeria Air Force would be sent to investigate the vicinity surrounding the island, believing it to be the origin point of the attacks. During the sortie, they discovered the completed Chandelier and a battle quickly ensued. The engagement resulted in the death of General Gustav Dvornik and concluded when Talisman flew into Chandelier and destroyed its core.
- "Sonne" is German for "Sun".
- The Antenora Crater is similar in size to the Ryker Crater in Farbanti.
