Karifa

Acirfa (カリファ) was a Marleyan naval port located on the continental mainland's northern coast.

War for Paradis arc
Upon arriving in Odiha, Yelena confesses to discussing a strategy with Eren Yeager to cripple Marley's military defenses with a partial rumbling in order to secure peace for Paradis Island for several decades to come. She had singled out Acirfa as the likely gathering point for a Global Allied Fleet which would inevitably be summoned after Eren's planned raid on Liberio. Despite her guarantee of a temporary peace with a strike against Acirfa, she had shown some concern regarding Fort Salta in southern Marley. With Eren leading a full-scale rumbling against the entire world, Yelena guesses that after destroying Acirfa, he would target Fort Salta in order to completely rid Marley of any weapons against the Founding Titan.

The port is one of the first locations on the Marleyan continent to be affected by the Rumbling, with the Global Allied Fleet making its stand along the coastline along with a Marleyan military artillery contingent waiting on the docks. As the Rumbling approaches the port, the Global Allied Fleet unleash a barrage of munitions fire onto the underwater Colossal Titans, but the barrage has no effect and the crews of the ships are vaporized by the sheer heat of the Titans. As the Global Allied Fleet is wiped out and the Titans arise towards the port, the artillery contingent opens fire on the arisen Titans, unloading a full barrage onto the wall of Titans. Unfortunately, the munitions barrage once again has no effect on the Titans, who continue their march toward the mainland without stop. As the Titans arrive on shore, the majority of Marleyan soldiers abandon their posts, retreating towards higher ground; as the soldiers retreat, they look on in fear at Eren's Founding Titan form as he tramples the entire port.

Trivia

 * Unlike the majority of Marleyan location names which are based in Latin or Italian nomenclature, "Acirfa" simply appears to be "Africa" backwards. This is also applicable to the original katakana in which the characters for Africa (アフリカ) are reversed. This may refer to the Marleyan continental mainland being based on the real-world continent of mirrored vertically.
 * If mirrored vertically, Acirfa's location according to Yelena appears to correspond roughly with in.
