Cavem Canus (a.k.a. Dingo City) was the name of the main Dingo city on Angel Island. After Echidnaopolis was invaded and destroyed following the forged alliance between the Dingo Regime and the Eggman Empire made by Kage Von Stryker, Cavem Canus was erected over top of its ruins. The city featured numerous concentration camps where Echidnas were enslaved and forced to endure gruelling labour and torture, and in many cases death. The city was erased atom-by-atom along with Kage Von Stryker by Enerjak in 3237, marking an end of the tyrants rule over the Dingoes. (StH: #138, #139, #181)
