Sword Princess are highly popular Combat summons in Elder Tale. As a result, many variations of this summon have been created.
Like other Combat summons, the Sword Princess will only appear for a moment to attack the enemy before disappearing. However, after the Catastrophe, it is possible to summon them outside of combat.
Sword Princess: Al Quinje
Sword Princess: Al Quinje (ソードプリンセス：アル・クィンジェ) was used by Roe2 in the invasion of Saphir by Wyverns. It is an extremely powerful summon that originates from Mare Tranquillitatis and cannot be found elsewhere on Theldesia. When summoned, this creature is capable of attacking multiple targets from great distances. It wields a harp, which it strums before each attack.
It seems to be an incarnation of one of the Ruquinjé, as they both have the symbol of the Alv on the veils covering their faces. However, Rquinje is spelled with kanji (which are also Chinese characters) as 六傾姫, while Al Quinje is spelled only in katakana. If it had a kanji form, it would likely be 二傾姫 (èr qīng zhěn, which transliterates to "two toppling princesses" or "second toppling princess").
Sword Princess: Lance Dísir
The name for Lance Dísir comes from the dís in Norse mythology.
