《太空戰士14：蒼天的伊修加爾德》（Final Fantasy XIV: Heavensward）《Final Fantasy XIV》的首部大型資料片，於2015年推出。不僅大幅擴展遊戲的世界觀與地圖，還導入新的劇情篇章、種族、職業以及高難度的副本與團隊挑戰，成為許多玩家心目中FF14最具代表性的資料片之一。登錄在PS3、PS4、Windows、Mac OS X。

世界設定在伊修加爾德（Ishgard）這座歷史悠久且孤立的城市國度，背景圍繞著持續千年的「龍詩戰爭」。伊修加爾德的人民與龍族之間的恩怨源遠流長，雙方仇恨深植於歷史與信仰之中。在經歷主線劇情「黑暗中的希望之火」（A Realm Reborn）後，被迫逃往伊修加爾德，試圖揭開這場戰爭背後的真相，並努力促成和平。

主角光之戰士在貝里昂（Count Edmont de Fortemps）家族的幫助下深入伊修加爾德的權力核心，逐步揭露龍詩戰爭並非單純的正邪對抗，而是人類與龍族雙方都有錯誤與背叛。故事最終帶領玩家進入「亞歷山大大聖堂」（The Vault），面對伊修加爾德最高宗教領袖主教索姆阿爾法尼（Thordan VII），並在決戰後揭開隱藏在戰爭背後的真相。

劇情強調「贖罪與寬恕」，角色塑造深刻，尤其是聖龍赫德拉菲爾（Hraesvelgr）與奈茲赫加爾（Nidhogg）之間的矛盾，使在面對敵人時能感受到龍族的悲劇與伊修加爾德的掙扎，展現《Final Fantasy》系列一貫擅長的情感敘事。延續《Final Fantasy XIV》的核心遊戲系統，在廣闊的開放世界中探索，並參與副本、挑戰強大的敵人。除新的擴充迷宮與任務外，有三種新設計的玩家對戰(PvP)。

該資料片導入新的等級上限（從50提升至60），以及三個全新的職業：

黑騎士（Dark Knight） – 以暗黑魔法強化自身的坦克職業，擅長吸收敵人攻擊並反擊。

機工士（Machinist） – 遠程物理輸出職業，使用槍械與機械裝置來攻擊敵人。

占星術士（Astrologian） – 療癒型職業，可利用星象進行治療或強化隊友，並使用卡牌系統增強團隊能力。

此外，還新增可操控的飛行坐騎，在特定區域自由飛行，這使得探索更加便利且富有樂趣。副本設計方面，新增的高難度團隊副本如「亞歷山大機械城」（Alexander）提供挑戰性的戰鬥與機關解謎，而極限模式的討伐戰則繼續考驗反應與團隊合作能力。資料片新增多個關鍵副本與挑戰：

亞歷山大機械城（Alexander） – 這是一座巨大的機械要塞，需要逐步深入，與守護機械體戰鬥，並面對最終BOSS「完美亞歷山大」。

伊甸之門（Eden’s Gate） – 高難度團隊副本，需團隊合作進行多階段戰鬥，每個階段都有獨特的機制與劇情演出。

尼德霍格之影（The Nidhogg Trial） – 與黑龍奈茲赫加爾的激戰，是劇情高潮的戰鬥之一，需要高度配合與準確的戰術執行。

此外，野外世界設計更加廣袤，包含冰天雪地的「庫爾札斯西部高地」、遼闊的「阿巴拉提亞雲海」及壯麗的「龍堡內地」。這些區域不僅環境設計細緻，還隱藏著許多支線任務與寶藏，等待深入探索。

當年在推出後獲得極高的市場評價，許多評論認為該資料片成功擴展《Final Fantasy XIV》的世界觀，並以引人入勝的劇情與出色的視覺設計獲得玩家青睞。IGN、GameSpot等主流媒體給予高度評價，認為該資料片的故事敘述方式和角色深度讓人印象深刻，特別是龍詩戰爭的悲壯與角色之間的矛盾描寫相當出色。

玩家社群對《Heavensward》普遍持正面態度，並認為這是《Final Fantasy XIV》走向巔峰的重要一步，將該遊戲從普通的線上遊戲提升為劇情驅動的RPG典範。其劇情不僅深化《FF14》宇宙，也為後續資料片（如《Stormblood》、《Shadowbringers》）奠定扎實的基礎。總體來說，《Heavensward》不僅強化《Final Fantasy XIV》的遊戲體驗，也讓該遊戲在全球市場中站穩腳步，成為線上遊戲市場的佼佼者。

Final Fantasy XIV: Heavensward is the first major expansion for Final Fantasy XIV, released in 2015. This expansion significantly broadened the game's world and map while introducing new story chapters, races, classes, and challenging dungeons and raids. It is regarded by many players as one of the most iconic expansions of FF14. The expansion launched on PS3, PS4, Windows, and Mac OS X.

The setting takes place in the ancient and isolated city-state of Ishgard, which serves as the focal point of the Dragonsong War, a conflict that has raged for a thousand years between the people of Ishgard and the dragon race. The roots of hatred and animosity between the two sides run deep, entrenched in history and faith. Following the events of the main storyline A Realm Reborn, the protagonist—the Warrior of Light—is forced to seek refuge in Ishgard, attempting to uncover the truth behind the war and striving for peace.

With the support of Count Edmont de Fortemps and his family, the Warrior of Light infiltrates Ishgard’s political and religious core, gradually revealing that the Dragonsong War is not a straightforward clash between good and evil but a tale marked by betrayals and mistakes on both sides. The story ultimately leads players to The Vault, where they confront Ishgard’s supreme religious leader, Archbishop Thordan VII. After a climactic battle, the hidden truths behind the war are finally brought to light.

The narrative heavily emphasizes themes of redemption and forgiveness, with deep character development. The conflict between the great wyrm Hraesvelgr and his vengeful brother Nidhogg highlights the tragedy of the dragon race and the struggles within Ishgard, showcasing the emotional storytelling that the Final Fantasy series is known for.

Heavensward builds upon the core gameplay of Final Fantasy XIV, allowing players to explore vast open-world environments, participate in dungeons, and engage powerful enemies. In addition to new dungeons and quests, the expansion introduces three new PvP modes.

The expansion raises the level cap from 50 to 60 and adds three new playable classes:

Dark Knight – A tank class that wields dark magic to enhance itself, capable of absorbing enemy attacks and retaliating.

Machinist – A ranged physical damage dealer who uses firearms and mechanical gadgets to attack enemies.

Astrologian – A healer class that harnesses the power of the stars to heal or enhance allies. This class also employs a card-based system to provide additional buffs to the party.

Additionally, Heavensward introduces flying mounts, allowing players to soar freely across specific zones, greatly enhancing exploration and adding a new layer of enjoyment to traversal.

The dungeon and raid design also receives significant updates, with challenging encounters like:

Alexander – A massive mechanical fortress that players must gradually conquer, facing mechanized guardians and ultimately confronting Perfect Alexander.

Eden’s Gate – A high-difficulty raid requiring teamwork across multiple phases, each with unique mechanics and narrative elements.

The Nidhogg Trial – A pivotal battle against the dark wyrm Nidhogg, marking one of the major climaxes in the storyline. This encounter demands precise execution and strong cooperation among party members.

The overworld is further expanded with new, visually stunning regions such as the frigid Coerthas Western Highlands, the vast Sea of Clouds, and the majestic Dravanian Forelands. These areas are richly designed and filled with side quests and hidden treasures awaiting exploration.

Upon release, Heavensward garnered widespread acclaim, with many critics praising the expansion for successfully broadening Final Fantasy XIV’s world and narrative depth. Reviewers from IGN and GameSpot highlighted the compelling story, strong character development, and the tragic yet beautiful portrayal of the Dragonsong War. The complex portrayal of the characters’ inner conflicts and Ishgard’s harsh reality left a lasting impression on players.

The Final Fantasy XIV community responded positively to Heavensward, with many considering it a pivotal step in the game’s evolution. It helped elevate Final Fantasy XIV from a standard MMORPG to a narrative-driven RPG, setting the foundation for future expansions such as Stormblood and Shadowbringers.

Overall, Heavensward not only enriched the gameplay experience of Final Fantasy XIV but also solidified the game's position as a leader in the global MMORPG market. This expansion is a testament to Final Fantasy XIV’s growing reputation as one of the most immersive and narratively compelling online games available.
